The Garfield Range is located at Lake Hazen which is the world's largest lake north of the Arctic Circle by volume and acts as a barrier between the lake and the Grant Land ice cap and nunataks of the United States Range to the north. The Gilman Glacier is one of the largest glaciers draining into Lake Hazen. To the est, the mountain range extends across the Hazen Plateau while, to the west, it runs virtually to the head of Tanquary Fiord. The mountains, which tower as much as 1,500 m (4,921 ft) above Lake Hazen, typically consists of steep snow-free slopes facing south, with north-facing slopes of shallow gradients covered in snow and ice. At intervals, the range is bisected by broad valleys 5 to 8 km (3.1 to 5.0 mi) in width that are occasionally filled by glacial tongues, such as the monumental Henrieta Nesmith Glacier that descends to within 4 km (2 mi) of Lake Hazen near its northwestern end.
