Fairweather Mountain, towering just fourteen miles from the Pacific Ocean, is the dominant peak in the Fairweather Range. The Fairweather Range is located at the southern end of the St. Elias Mountains, along the coast of the northern Alaska Panhandle. Bordered on the west by the spectacular Tatshenshini and Alsek Rivers, and on the north by Glacier Bay, it is quite awesome for its vertical relief and incredible snow pack. The mountains rise almost three vertical miles directly out of the sea, with the 15,300 foot summit of Mount Fairweather only 24 miles from the coast. It is a broad mountain with a sharp icy summit, and contrary to the implications of its name, is subject to some of the world’s worst weather. Its huge Fairweather Glacier flows beautifully from the mountain’s southern flanks to the sea.

Best time to travel

The best time to climb here is May through early July. The weather follows a maritime pattern, resulting in a healthy snow pack and warmer than average winter and early spring temperatures. Summer temps average 42 to 62 degrees, but tends to get stormy, and the wind and snow on the high peaks can be deadly. Its extreme relief and large annual snowfall makes it very glaciated and beautiful. The south face’s 10,000+ ft. relief is bisected by the Carpe’ Ridge which is featured in Steve Roper’s “50 Classic Climbs of North America”.

We will fly into 8,000 ft above sea level on the Grand Plateau Glacier and spend a couple of days acclimatizing before moving up.

As an additional note it must be mentioned that while the majority of the mass of the peak resides within the state of Alaska, the summit itself belongs to British Columbia in Canada. The highest mountain entirely within British Columbia is Mount Waddington (4,016 metres) in the Coast Mountains. It was named in 1918 by the Geographic Board of Canada for Alfred Waddington who, from 1858 to 1872, encouraged the creation of a transcontinental route to the Pacific via Bute Inlet, the head of which is 60 kilometers south of the mountain.

Climbing Preparations and Equipment

When planning an ascent of Fairweather Mountain, climbers must meticulously prepare, ensuring they have the appropriate gear and equipment for a safe and successful climb. This mountain, known for its severe weather conditions and challenging terrain, demands respect and thorough preparation.

Essential Climbing Gear

  • Mountaineering Boots: A sturdy pair of insulated, waterproof mountaineering boots is crucial. These should be compatible with crampons for ice climbing.
  • Crampons: Steel crampons with anti-balling plates are necessary for the icy and snowy surfaces you will encounter.
  • Ice Axe: An ice axe suitable for technical mountaineering is vital for both ascent and descent. This tool is essential for balance, climbing steep sections, and self-arresting in case of a slip or fall.
  • Climbing Harness: A well-fitting climbing harness equipped with gear loops to hold additional equipment is important.
  • Helmet: A climbing helmet is necessary to protect against falling rock and ice, which are common hazards on mountain climbs.

Mountaineering Boots

Recommended Clothing

  • Insulating Layers: Climbers should wear multiple layers of clothing that can be adjusted as temperatures change. These include a base layer that wicks moisture away from the body, an insulating middle layer, and a waterproof and windproof outer layer.
  • Down Jacket: A high-quality down jacket is essential for warmth, especially during rests or in case of unexpected weather changes.
  • Gloves: Waterproof gloves with a separate insulating layer are best to keep hands warm and dry.
  • Beanie and Balaclava: A warm beanie and a balaclava for face protection against cold winds are important, especially at higher altitudes where temperatures drop significantly.

Safety Gear

  • GPS and Maps: Navigation tools such as a GPS device, along with traditional maps and compass, are essential for finding your way, especially in poor visibility conditions.
  • First Aid Kit: A well-stocked first aid kit tailored for mountaineering should include items for treating frostbite, cuts, and altitude sickness.
  • Communication Device: A satellite phone or a two-way radio can be lifesaving in emergencies, providing a way to call for help if necessary.
  • Emergency Shelter: An emergency bivouac sack or a lightweight tent can be crucial if sudden weather changes force an unplanned overnight stay on the mountain.

Conservation and Environmental Impact

Environmental Vulnerabilities of Fairweather Mountain

The juxtaposition of the mountain’s harsh climate and its coastal proximity creates a fragile ecological balance that is sensitive to changes, particularly those brought on by human activities. Such sensitivity underscores the need for responsible visitation practices.

Active Conservation Measures

  • Protected Natural Areas: Significant portions of the surrounding terrain, including areas within Tatshenshini-Alsek Provincial Park, are legally protected to prevent undue commercial and industrial impact, thus preserving the landscape and its biological communities.
  • Scientific Studies: Regular environmental studies help track the condition of ecosystems, measuring the impact of human presence and guiding the development of policies aimed at minimizing ecological disruption. Visitors can aid these efforts through contributions and volunteer activities.
  • Partnerships with Indigenous Populations: Conservation strategies frequently involve working with local indigenous groups, who possess an intrinsic understanding of the ecosystem. These partnerships help to ensure that land management practices incorporate traditional ecological knowledge.

Best Practices for Environmental Preservation

Adhering to the following best practices is crucial for all visitors to help preserve the integrity of Fairweather Mountain:

  • Adopt Leave No Trace Ethics: Prepare thoroughly, dispose of all waste correctly, leave natural objects undisturbed, maintain a safe distance from wildlife, show consideration to fellow visitors, and reduce campfire impacts by favoring portable stoves.
  • Efficient Waste Management: Carry out all garbage and leftover food. Use environmentally friendly products and ensure all washing occurs well away from any water bodies to avoid contamination.
  • Wildlife Respect: Watch wildlife from a distance, do not attempt to interact with them, and absolutely refrain from feeding them. Feeding wildlife can harm their health and disrupt their natural behavior patterns.

Embracing these stewardship principles ensures that Fairweather Mountain remains a spectacular and healthy environment for generations to come. It’s through our collective efforts that we can contribute to the ongoing preservation of this extraordinary natural wonder.
