Scott Lake

Scott Lake. It is a significant proglacial lake located within the Wrangell-St. Elias National Park and Preserve in southeastern Alaska. Formed by the meltwater of the retreating Scott Glacier, the lake is part of the headwaters of the Tana River, which eventually flows into the Gulf of Alaska. Its dynamic nature and remote setting make it a notable feature for scientific study and wilderness recreation.

Geography

Scott Lake is situated in the Saint Elias Mountains, a major mountain range that includes peaks like Mount Saint Elias and forms part of the border between Alaska and the Yukon. The lake is fed directly by the terminus of the Scott Glacier, a valley glacier originating from the extensive Bagley Icefield. Its outflow forms the beginning of the Tana River, a tributary to the Chitina River, which itself joins the Copper River. The surrounding terrain is characterized by rugged alpine tundra, moraine deposits, and dramatic cirques, with the lake's size and depth fluctuating seasonally with glacial melt. This region is part of the larger Pacific Coast Ranges and experiences a high-latitude oceanic climate influenced by the Pacific Ocean.

History

The area was historically traversed by Ahtna and Eyak peoples, who utilized the Copper River watershed for subsistence. European exploration increased following the Alaska Purchase in 1867, with figures like geologist Alfred Hulse Brooks of the United States Geological Survey mapping the region. The lake and its parent glacier were likely named for early 20th-century explorer and geologist Robert L. Scott. The establishment of the Wrangell-St. Elias National Park and Preserve in 1980, later designated a UNESCO World Heritage Site, placed the lake within a protected area managed by the National Park Service. Its history is intrinsically linked to the study of glaciology, particularly documenting the rapid retreat of Alaskan glaciers since the Little Ice Age.

Ecology

The lake's cold, often sediment-laden waters support a specialized ecosystem. Phytoplankton communities are limited by low light penetration and temperature, while the benthic zone may host chironomidae larvae and other invertebrates adapted to glacial environments. The outflowing Tana River provides spawning habitat for Pacific salmon species, including sockeye salmon and coho salmon, which are prey for brown bear and bald eagle. The surrounding alpine tundra supports hardy vegetation like Dryas and saxifrage, and fauna such as the Dall sheep, hoary marmot, and ptarmigan. This area forms a corridor within the Northern Pacific coastal forests ecoregion.

Recreation

Access is challenging, typically requiring a flight from Cordova or Yakutat to a nearby airstrip, followed by backpacking or mountaineering. The lake is a destination for wilderness backpacking, technical climbing on nearby peaks, and wildlife photography, particularly of brown bear and migratory birds. It serves as a base camp for expeditions onto the Scott Glacier and ascents in the Saint Elias Mountains. All activities are governed by strict Leave No Trace principles due to the fragile environment and its location within the national park. The National Park Service does not maintain developed facilities in the immediate vicinity.

Management

Primary management authority lies with the National Park Service under the regulations of the Wrangell-St. Elias National Park and Preserve. Key concerns include monitoring glacial retreat impacts, protecting water quality from potential future human impacts, and preserving the wilderness character as defined by the Wilderness Act. Management coordinates with the Alaska Department of Fish and Game on Pacific salmon fisheries in the downstream Tana River and Copper River systems. Scientific research, often conducted in partnership with institutions like the University of Alaska Fairbanks and the United States Geological Survey, informs stewardship decisions. The overarching goal is to balance preservation with limited, non-motorized recreational use.
