New Zealand stands as one of the world's most geologically dynamic and fascinating countries, showcasing an extraordinary array of natural features that tell the story of millions of years of Earth's evolution. From the explosive power of active volcanoes to the rhythmic eruptions of geysers and the majestic beauty of glacier-carved fjords, this island nation offers a living laboratory for understanding our planet's geological processes. These remarkable features not only attract millions of tourists each year but also provide scientists with invaluable opportunities to study volcanic activity, geothermal systems, and glacial geology in real-time.

The geological diversity of New Zealand is no accident. The country sits astride the boundary between two massive tectonic plates, creating conditions that have shaped its dramatic landscape over millions of years. This unique position has given rise to some of the most spectacular geological phenomena on Earth, making New Zealand a must-visit destination for nature enthusiasts, adventure seekers, and anyone fascinated by the raw power of our planet.

The Tectonic Foundation: New Zealand's Position on the Pacific Ring of Fire

New Zealand's existence and its volcanoes are almost totally the result of the Pacific and Indian-Australian plate boundary, positioning the country within one of the most geologically active regions on Earth. New Zealand is located on the Pacific Ring of Fire, which stretches for about 40,000 km around the Pacific Ocean, where the tectonic plate of the Pacific collides with several surrounding continental plates. This collision zone creates the perfect conditions for volcanic activity, earthquakes, and the formation of dramatic topographical features.

The interaction between these tectonic plates has been ongoing for millions of years, continuously reshaping the landscape and creating new geological features. This dynamic process means that New Zealand is constantly evolving, with volcanic eruptions, earthquakes, and geothermal activity serving as reminders of the powerful forces at work beneath the surface. Understanding this tectonic setting is crucial to appreciating the full scope of New Zealand's geological wonders.

Geothermal Wonders: New Zealand's Spectacular Geysers

The Rotorua Region: New Zealand's Geothermal Heartland

The geothermal activity in New Zealand reaches its most spectacular expression in the Rotorua region of the North Island. Sitting within the Pacific Rim of Fire, the region offers some of the world's most active geothermal activity. This area has become synonymous with geothermal phenomena, drawing visitors from around the globe to witness the Earth's internal heat manifesting at the surface in dramatic and beautiful ways.

Rotorua has earned the nickname "Sulphur City" because of the hydrogen sulphide emissions from the activity which gives it a "rotten eggs" smell, though this distinctive aroma is simply a natural part of life in this geothermal wonderland. The city and its surrounding areas have adapted to living alongside these powerful natural forces, incorporating geothermal energy into daily life for heating, cooking, and tourism.

Pōhutu Geyser: The Southern Hemisphere's Largest Active Geyser

The crown jewel of Rotorua's geothermal attractions is undoubtedly the Pōhutu Geyser, located in the Te Whakarewarewa Thermal Valley. The geyser is the largest in the southern hemisphere and among the most active in the area, erupting up to twenty times per day at heights of up to 30 m (98 ft). This remarkable consistency makes Pōhutu one of the most reliable geysers on Earth, offering visitors an excellent chance of witnessing its spectacular eruptions.

The legendary Pohutu Geyser in Te Puia erupts to a height of 30m (100 feet) up to 20 times a day, and once erupted non-stop for more than 250 days. This extraordinary endurance record demonstrates the immense geothermal power beneath the surface. The geyser's name, Pōhutu, means "constant splashing" in Māori, a fitting description for this natural wonder that has been captivating observers for generations.

The mechanism behind Pōhutu's eruptions is a fascinating example of geothermal processes at work. Underground water is heated by volcanic activity deep beneath the surface, creating pressure that eventually forces superheated water and steam upward through channels in the rock. When this pressure is released, the result is the spectacular fountain of water and steam that characterizes a geyser eruption.

The Whakarewarewa Thermal Valley

Just 3 km south of Rotorua town lies the Te Whakarewarewa thermal reserve with its two famed geysers and more than 500 hot springs. This concentration of geothermal features makes Whakarewarewa one of the most geothermally active areas in New Zealand. Whakarewarewa has the largest remaining concentration of geysers in New Zealand, making it an essential destination for anyone interested in geothermal phenomena.

The thermal valley is not just a tourist attraction but also home to a living Māori village where residents have utilized geothermal energy for centuries. The indigenous people of this area have developed sophisticated methods of harnessing the Earth's heat for cooking, bathing, and heating their homes. This integration of traditional culture with natural geothermal resources creates a unique cultural and geological experience that cannot be found anywhere else in the world.

Other Notable Geothermal Areas

Beyond Rotorua, New Zealand boasts several other remarkable geothermal areas. Hell's Gate boasts the largest mud volcano and largest hot waterfall in the Southern Hemisphere, offering visitors a different perspective on geothermal activity. The site features bubbling mud pools, steaming vents, and therapeutic hot springs that have been used for healing purposes for generations.

Waimangu Volcanic Valley was created in 1886 when Mt Tarawera erupted, destroying everything in its wake and forming the seven craters that make up the valley today. This relatively young geothermal area demonstrates how quickly the landscape can change due to volcanic activity. The valley features a range of geothermal phenomena, including hot springs, steaming cliffs, and the world's largest hot water spring.

The Lady Knox Geyser, located in the Waiotapu thermal area, offers a unique spectacle. It is artificially induced but produces a jet of water reaching up to 20 metres/65 feet and can last for over an hour depending on the weather. While not entirely natural, this geyser demonstrates the power of geothermal pressure and has become a popular daily attraction.

Conservation and Management of Geothermal Resources

The geothermal features of Rotorua have faced challenges over the years due to human activity. In 1985 the then Ministry of Energy published a comprehensive report concluding that there had been a dramatic decrease in natural activity at Whakarewarewa, including a 30% drop in natural heat flow between 1967 and 1985. This decline was attributed to excessive extraction of geothermal water from wells in the area.

In response to these concerns, the Government responded by embarking on a programme of compulsory well closure within 1.5 km of Pohutu Geyser. This conservation effort has helped protect these natural wonders for future generations, demonstrating the importance of balancing human needs with environmental preservation. Today, strict regulations govern geothermal resource use in the Rotorua area to ensure the long-term sustainability of these remarkable features.

Volcanic Powerhouses: New Zealand's Active Volcanoes

The Taupo Volcanic Zone

The region of volcanic activity that occurs from Mt Ruapehu to White Island in the Bay of Plenty is known collectively as the Taupō Volcanic Zone, and volcanic activity in the zone started about 2 million years ago and continues today. This volcanic zone represents one of the most active areas of volcanism in the world, stretching approximately 350 kilometers through the North Island.

The Taupo Volcanic Zone is characterized by a diverse range of volcanic features, from massive stratovolcanoes to calderas, geothermal fields, and volcanic vents. This concentration of volcanic activity is directly related to the subduction of the Pacific Plate beneath the Australian Plate, which creates the conditions necessary for magma generation and volcanic eruptions.

Mount Ruapehu: New Zealand's Largest Active Volcano

Mount Ruapehu is an active stratovolcano at the southern end of the Taupō Volcanic Zone and the largest active volcano in New Zealand, with the highest point in the North Island at 2,797 m. This massive volcano dominates the landscape of Tongariro National Park and serves as a year-round destination for outdoor enthusiasts, hosting ski fields in winter and hiking trails in summer.

The deep, active crater is between the peaks and fills with water between major eruptions, being known as Crater Lake (Māori: Te Wai ā-moe). This crater lake is not just a scenic feature but also a critical indicator of volcanic activity. The lake's temperature, color, and chemistry are constantly monitored by scientists, as changes in these parameters can signal increased volcanic unrest.

Ruapehu is a complex stratovolcano constructed during at least four cone-building episodes dating back to about 200,000 years ago. This long history of volcanic activity has created the mountain's distinctive profile and complex internal structure. The volcano has undergone numerous eruptions throughout its history, with a series of subplinian eruptions taking place between about 22,600 and 10,000 years ago.

Recent Eruptions and Volcanic Hazards

Ruapehu erupted in 1945–46 and again in 1995–96, with both eruption sequences causing significant disruption to the region. The 1995-96 eruptions produced more than 7 million tonnes of ash, which contaminated water supplies, destroyed crops, led to the deaths of livestock, damaged turbines at the Rangipo power station, caused airport closures as far away as Auckland and Wellington, and resulted in ski field closures costing the region an estimated $100 million in lost revenue.

The main volcanic hazard on Ruapehu is lahar, which are fast-moving volcanic mud flows like flash floods that occur during eruptions when water in the lake is ejected and flows at speed down valleys as a flash flood – mixing with ash, rocks and snow on the way down. These lahars pose a significant threat to infrastructure and communities in the valleys below the volcano.

One of the most tragic events in New Zealand's volcanic history occurred in 1953. In the 1945 eruptions, rubble had built up around Ruapehu's Crater Lake, and in 1953 the rubble collapsed, causing the lake to burst its banks, and the flow of water and rocks knocked over a railway bridge, causing a train to tumble into the river below, drowning 151 people. This disaster led to improved monitoring and warning systems for volcanic hazards in New Zealand.

Mount Tongariro and Mount Ngāuruhoe

Both Maori and geologists consider Ngauruhoe to be part of the Tongariro system, and these volcanoes are all less than 500,000 years old and still active. The Tongariro complex first became active around 260,000 years ago, and its twelve or more composite cones have erupted intermittently since then.

Mount Ngāuruhoe, with its distinctive conical shape, gained international fame as the filming location for Mount Doom in Peter Jackson's "The Lord of the Rings" trilogy. It pours out ash about once every six years, with large eruptions in 1870, in the late 1940s, and in 1954, and the most recent eruption was in 1975, when huge blocks of red-hot lava were thrown many kilometres from the mountain.

Mt Tongariro's active Red Crater last emitted ash in 1926, and there were eruptions from the Te Maari craters on Mt Tongariro's northern slopes on 6 August 2012 and 21 November 2012. These recent eruptions served as reminders that these volcanoes remain active and potentially dangerous, despite long periods of quiescence.

Volcanic Monitoring and Safety

Eruptions can occur at any time, with little or no warning, making continuous monitoring essential for public safety. New Zealand has developed sophisticated volcano monitoring systems that track seismic activity, ground deformation, gas emissions, and changes in crater lake temperature and chemistry. These systems provide early warning of potential eruptions, allowing authorities to implement safety measures and evacuate at-risk areas when necessary.

The New Zealand Volcanic Alert Level system evaluates the current level of volcanic unrest or eruption, is set by GeoNet based on volcano monitoring data, and has six Volcanic Alert Levels, ranging from no volcanic unrest, through two levels of volcanic unrest, to three levels of volcanic eruption. This system helps communicate volcanic risk to the public and guides decision-making for park management and emergency response.

Tongariro National Park: A UNESCO World Heritage Site

Tongariro National Park, which encompasses Mount Ruapehu, Mount Tongariro, and Mount Ngāuruhoe, holds the distinction of being New Zealand's first national park and one of the oldest national parks in the world. The park was gifted to the nation by Māori chief Te Heuheu Tukino IV in 1887 to protect the sacred mountains from European settlement and development.

The park has been recognized as a UNESCO World Heritage Site for both its natural and cultural significance. It represents an outstanding example of volcanic processes and contains spectacular volcanic features, while also holding deep spiritual significance for the Māori people. The Tongariro Alpine Crossing, one of New Zealand's most popular day hikes, allows visitors to experience the volcanic landscape up close, passing through diverse terrain including active craters, emerald lakes, and ancient lava flows.

Majestic Fjords: Glacial Masterpieces of the South Island

Formation of New Zealand's Fjords

While the North Island showcases New Zealand's volcanic power, the South Island reveals the dramatic sculpting power of ice. The fjords of Fiordland, located in the southwestern corner of the South Island, represent some of the most spectacular examples of glacial erosion on Earth. These deep, steep-sided valleys were carved by massive glaciers during the last ice age, which ended approximately 10,000 to 12,000 years ago.

During the ice age, enormous glaciers flowed from the mountains toward the sea, grinding away at the bedrock beneath them. The immense weight and movement of these ice rivers carved deep U-shaped valleys through the landscape. When the climate warmed and the glaciers retreated, the sea flooded these valleys, creating the dramatic fjords we see today. The steep cliffs that characterize these fjords are the result of this glacial erosion, with some walls rising nearly vertically from the water for hundreds of meters.

Milford Sound: The Jewel of Fiordland

Milford Sound stands as perhaps the most famous and visited of New Zealand's fjords, often described as the "eighth wonder of the world." This spectacular fjord extends 15 kilometers inland from the Tasman Sea and is surrounded by sheer rock faces that rise up to 1,200 meters above the water. The fjord's most iconic feature is Mitre Peak, a distinctive mountain that rises 1,692 meters directly from the water, creating one of the most photographed scenes in New Zealand.

The fjord receives an extraordinary amount of rainfall, averaging around 6,800 millimeters per year, making it one of the wettest places in New Zealand. This abundant rainfall creates hundreds of temporary waterfalls that cascade down the cliff faces after storms, adding to the fjord's dramatic beauty. The most permanent and impressive of these is Stirling Falls, which plunges 155 meters into the fjord, and Bowen Falls, which drops 162 meters.

The underwater environment of Milford Sound is equally remarkable. A permanent layer of fresh water from rainfall and runoff sits atop the denser seawater, creating a unique ecosystem. This freshwater layer is stained dark by tannins from the surrounding vegetation, blocking much of the sunlight. As a result, deep-water species such as black coral can be found at unusually shallow depths, sometimes as shallow as 10 meters below the surface.

Doubtful Sound: The Sound of Silence

Doubtful Sound, the second-largest fjord in Fiordland, offers a more remote and pristine experience than its famous neighbor. The fjord is three times longer and ten times larger in area than Milford Sound, extending 40 kilometers inland and branching into several arms. Its name comes from Captain James Cook, who in 1770 was doubtful whether the winds in the fjord would be sufficient to allow his ship to sail back out to sea.

Doubtful Sound is often called "The Sound of Silence" due to its remote location and the profound quiet that can be experienced there. The fjord is less accessible than Milford Sound, requiring both a boat trip across Lake Manapouri and a coach journey over Wilmot Pass to reach it. This relative inaccessibility has helped preserve its pristine character and abundant wildlife.

The fjord is home to a resident population of bottlenose dolphins, as well as fur seals and occasionally Fiordland crested penguins. The surrounding forests are inhabited by numerous bird species, including the rare and endangered takahe, a flightless bird once thought to be extinct. The combination of dramatic scenery, abundant wildlife, and profound tranquility makes Doubtful Sound a truly special destination.

Other Notable Fjords

While Milford and Doubtful Sounds receive the most attention, Fiordland contains fourteen fjords, each with its own unique character. Dusky Sound, the largest of the fjords, was the first to be explored by Captain Cook in 1773. The fjord is extremely remote and can only be accessed by boat or by undertaking a challenging multi-day hiking track.

Preservation Inlet, located at the southern end of Fiordland, offers some of the most pristine wilderness in New Zealand. The area is so remote that it remains largely unexplored, with dense temperate rainforest covering the surrounding mountains. George Sound, Caswell Sound, and Nancy Sound are other notable fjords, each offering spectacular scenery and opportunities for wilderness experiences.

Fiordland National Park

The fjords are protected within Fiordland National Park, New Zealand's largest national park, covering 1.2 million hectares. The park was established in 1952 and became part of the Te Wahipounamu World Heritage Area in 1990, recognized for its outstanding natural values and as one of the great wilderness areas of the Southern Hemisphere.

The park encompasses not only the fjords but also mountains, lakes, rivers, and vast tracts of ancient temperate rainforest. The landscape is characterized by dramatic relief, with mountains rising directly from sea level to heights of over 2,000 meters. This extreme topography, combined with the region's high rainfall, creates an environment of exceptional beauty and ecological significance.

The Unique Ecosystem of the Fjords

The fjords support a unique ecosystem that combines marine and terrestrial elements. The steep-sided valleys create microclimates that support diverse plant communities, from coastal podocarp forests to alpine herb fields. The forests are dominated by southern beech, rimu, and other native species, many draped with mosses and lichens that thrive in the moist environment.

The marine environment of the fjords is equally diverse. The mixing of fresh and salt water creates unique conditions that support a wide variety of marine life. Fish species include blue cod, red cod, and the rare Fiordland skate. The fjords also provide important habitat for marine mammals, including fur seals, which can often be seen basking on rocks near the water's edge.

The bird life in Fiordland is particularly notable. The region is home to several endemic species, including the Fiordland crested penguin, which nests in caves and under overhanging vegetation along the fjord shores. The forests echo with the calls of native birds such as the tui, bellbird, and the distinctive kea, the world's only alpine parrot. The critically endangered kakapo, a large flightless parrot, has been successfully reintroduced to predator-free islands in the region.

The Interconnection of New Zealand's Geological Features

While geysers, volcanoes, and fjords might seem like separate phenomena, they are all part of New Zealand's complex geological story. The same tectonic forces that create volcanic activity in the North Island also contribute to the mountain building that led to the formation of the Southern Alps, from which the glaciers that carved the fjords descended.

The Pacific and Australian plates don't just collide in one way across New Zealand. In the North Island, the Pacific Plate subducts beneath the Australian Plate, creating the conditions for volcanism and geothermal activity. In the South Island, the relationship is reversed, with the Australian Plate subducting beneath the Pacific Plate. This creates a different type of tectonic environment, characterized by uplift and mountain building rather than volcanism.

The Alpine Fault, which runs along much of the length of the South Island, marks the boundary between these plates. This fault is capable of producing major earthquakes and has been responsible for uplifting the Southern Alps over millions of years. The mountains created by this uplift provided the high-altitude environment necessary for the formation of the massive glaciers that carved the fjords during ice ages.

Tourism and Economic Impact

New Zealand's unique geological features are not just scientifically significant; they are also major drivers of the country's tourism industry. Millions of visitors come to New Zealand each year specifically to experience these natural wonders. The tourism industry built around these features contributes billions of dollars to the New Zealand economy and supports thousands of jobs in regional communities.

Rotorua has developed into a major tourist center, with its geothermal attractions forming the backbone of the local economy. Visitors can experience Māori culture alongside geothermal wonders, creating a unique cultural and natural tourism product. The city offers a range of experiences, from viewing geysers and mud pools to bathing in natural hot springs and experiencing traditional Māori hangi meals cooked using geothermal heat.

Tongariro National Park attracts hundreds of thousands of visitors annually, with the Tongariro Alpine Crossing being one of New Zealand's most popular day hikes. The park's ski fields on Mount Ruapehu provide winter recreation opportunities, though volcanic activity occasionally disrupts operations. The park's dual World Heritage status, recognizing both natural and cultural values, makes it a destination of international significance.

Milford Sound receives over half a million visitors each year, making it one of New Zealand's most visited natural attractions. The journey to Milford Sound, whether by road through the Homer Tunnel or by scenic flight, is itself a major attraction. Cruise operators, kayaking companies, and scenic flight operators all contribute to the tourism economy of the region. Doubtful Sound, while less visited, offers a more exclusive wilderness experience that appeals to travelers seeking solitude and pristine nature.

Scientific Research and Monitoring

New Zealand's geological features provide invaluable opportunities for scientific research. The country's volcanoes are among the most closely monitored in the world, with networks of seismometers, GPS stations, gas sensors, and other instruments providing real-time data on volcanic activity. This monitoring serves both scientific and public safety purposes, helping researchers understand volcanic processes while also providing early warning of potential eruptions.

GeoNet, New Zealand's geological hazard monitoring system, operates a comprehensive network of instruments across the country. The data collected helps scientists understand not only volcanic activity but also earthquakes, landslides, and other geological hazards. This research has contributed significantly to global understanding of volcanic and seismic processes.

The geothermal areas of New Zealand are also subjects of ongoing research. Scientists study the chemistry of geothermal fluids, the biology of thermophilic organisms that live in hot springs, and the potential for geothermal energy development. New Zealand has become a world leader in geothermal energy technology, with several power stations harnessing geothermal heat to generate electricity.

Research in Fiordland focuses on understanding the unique ecosystems of the fjords and the impacts of climate change on these environments. Scientists monitor changes in water temperature, salinity, and marine life populations. The region also serves as a natural laboratory for studying glacial geology and the long-term effects of glaciation on landscapes.

Conservation Challenges and Efforts

Protecting New Zealand's geological features while allowing public access presents ongoing challenges. The popularity of these attractions can lead to environmental impacts, from erosion on hiking trails to disturbance of wildlife. Park managers must balance conservation needs with tourism demands, implementing measures such as visitor limits, track maintenance programs, and education initiatives.

Climate change poses particular challenges for New Zealand's geological features. Rising temperatures are affecting the glaciers that remain in the Southern Alps, with many showing significant retreat. Changes in precipitation patterns could affect the character of the fjords and the ecosystems they support. Increased frequency of extreme weather events may impact visitor access and safety.

In the geothermal areas, the challenge is to balance resource use with conservation. While geothermal energy is a valuable renewable resource, excessive extraction can damage surface features. The experience of Rotorua in the 1970s and 1980s, when overuse led to declining geyser activity, has informed more sustainable management practices. Today, strict regulations govern geothermal resource use, with protected zones around significant features.

Invasive species pose a significant threat to the ecosystems associated with New Zealand's geological features. Introduced predators such as stoats, rats, and possums threaten native bird populations, while invasive plants can alter forest composition. Conservation efforts include extensive predator control programs, particularly in areas with endangered species. Some offshore islands in Fiordland have been made predator-free, providing safe havens for threatened species.

Cultural Significance

For Māori, the indigenous people of New Zealand, many of these geological features hold deep spiritual significance. The volcanoes of Tongariro National Park are considered sacred ancestors, and the geothermal areas of Rotorua have been used for centuries for cooking, bathing, and healing. The gift of the Tongariro mountains to the nation by Te Heuheu Tukino IV was a visionary act that ensured their protection while acknowledging their spiritual importance.

Māori have developed extensive traditional knowledge about these geological features, including understanding of volcanic activity patterns, the properties of geothermal waters, and the navigation of the fjords. This traditional knowledge is increasingly recognized as valuable alongside scientific understanding, with many conservation and tourism initiatives now incorporating Māori perspectives and management practices.

The integration of Māori culture with geological tourism has created unique experiences that educate visitors about both natural and cultural heritage. At Rotorua's geothermal attractions, visitors can learn about traditional uses of geothermal resources while experiencing Māori cultural performances and cuisine. This cultural dimension adds depth to the visitor experience and helps ensure that tourism benefits local Māori communities.

Future Outlook

New Zealand's geological features will continue to evolve and change. The volcanoes will erupt again, geysers will continue their rhythmic displays, and the fjords will slowly respond to changing climate conditions. Understanding and preparing for these changes is crucial for both public safety and conservation.

Advances in monitoring technology will improve our ability to predict volcanic eruptions and understand geothermal systems. Remote sensing, including satellite-based monitoring, provides new tools for tracking changes in volcanic activity and ground deformation. Improved computer modeling helps scientists better understand the complex processes that drive volcanic and geothermal activity.

The challenge for the future will be to maintain the balance between access, conservation, and safety. As tourism continues to grow, innovative management strategies will be needed to protect these features while allowing people to experience them. This may include developing new technologies for visitor management, creating alternative attractions to reduce pressure on the most popular sites, and enhancing education programs to promote responsible tourism.

Climate change adaptation will become increasingly important. This may involve adjusting management practices to account for changing conditions, protecting vulnerable ecosystems, and preparing for potential increases in volcanic and seismic activity that some scientists predict could result from climate-related changes in ice loading and sea levels.

Practical Information for Visitors

For those planning to experience New Zealand's geological wonders firsthand, careful planning is essential. The geothermal areas of Rotorua are easily accessible year-round, with well-developed infrastructure and a range of accommodation options. Visitors should allocate at least two to three days to fully experience the region's attractions, including geothermal parks, Māori cultural experiences, and outdoor activities.

Visiting the volcanoes of Tongariro National Park requires more preparation. The Tongariro Alpine Crossing, while spectacular, is a challenging full-day hike that requires good fitness and appropriate equipment. Weather conditions can change rapidly in the mountains, and the track is sometimes closed due to volcanic activity or severe weather. Winter visits require mountaineering experience and equipment. Always check current conditions and volcanic alert levels before visiting.

Accessing the fjords of Fiordland requires significant travel time. Milford Sound can be reached by a scenic but winding road from Te Anau, taking approximately two hours. Many visitors choose to fly or take a bus tour. Doubtful Sound requires a boat trip across Lake Manapouri followed by a coach journey over Wilmot Pass. Both fjords can be experienced on day trips, but overnight cruises offer a more immersive experience and the opportunity to see the fjords at dawn and dusk when they are most atmospheric.

Safety should always be a priority when visiting these geological features. In geothermal areas, stay on marked paths and boardwalks, as the ground can be unstable and water temperatures can be dangerously hot. In volcanic areas, be aware of current alert levels and follow all safety instructions. In the fjords, weather can change rapidly, and visitors should be prepared for rain and cool temperatures even in summer.
