Mount Tlingit is a 12,606-foot (3,842-meter) mountain summit in Alaska, United States.
Mount Tlingit is part of the Fairweather Range which is a subrange of the Saint Elias Mountains. The glaciated peak is located in Glacier Bay National Park, 2.30NaN0 southeast of the Canada–United States border, and 4.80NaN0 east of Mount Fairweather, which is the highest peak in the Fairweather Range.[1] Tlingit ranks as the sixth-highest peak in the park and 76th-highest in Alaska.[2] Precipitation runoff and meltwater from its surrounding glaciers drains into Glacier Bay Basin and the Gulf of Alaska. The mountain's toponym has not been officially adopted by the United States Board on Geographic Names. Mount Tlingit should not be confused with officially-named Tlingit Peak (3,169 feet) which is also within Glacier Bay National Park.[3]
Based on the Köppen climate classification, Mount Tlingit has a subarctic climate with cold, snowy winters, and cool summers.[4] Winter temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports the Margerie Glacier to the east of the summit and Fairweather Glacier to the southwest. The months May through June offer the most favorable weather for viewing or climbing.
