The Great Glacier (Engl. Great Glacier , dt. "Great Glacier") is a 23 km long valley glaciers in the Boundary Ranges in British Columbia (Canada) and Alaska (USA).
geography
The mean 1.8 km wide glacier on the southeast edge of the Stikine Icecap is almost entirely in British Columbia. The glacier's nutrient area is on the southwest flank of Mount Gibbons at an altitude of about 1200 m . The Great Glacier extends only a few kilometers to US territory in the west. The Castle Mountain , a Grenzgipfel, overlooks the glacier in the southwest. The Great Glacier flows in an east-southeast direction and ends at a height of about 30 m . The glacier tongue is located on the west bank of a glacial edge lake , which is separated from the Stikine River by an 800 m wide strip of land . A short drain leads the water to the Stikine River. The glacier edge lake measures 6.7 km in north-south direction and 3.7 km in west-east direction.
The 9,300 hectare Great Glacier Provincial Park includes the lower section of the Great Glacier and the glacial rim lake and extends to the west bank of the Stikine River.
Glacier development
The glacier tongue is steadily retreating. The surface area of the glacier edge lake is growing accordingly.
