The Stikine Icecap (also called Stikine Icefield ) is a 21,876 km² ice cap in the Boundary Ranges of the Coast Mountains .
It stretches along the border between the Alaska Panhandle and the Canadian province of British Columbia . It is bounded in the south by the Stikine River and in the north by the Taku River .
The ice cap is the headwaters of several tributaries of the Taku River and Stikine River. It feeds several glaciers. The Wright Glacier flows north to the Taku River. LeConte , Baird , Dawes , South-Sawyer and Sawyer stream west and end right on the ocean. The Patterson Glacier also flows west, but ends 10 km offshore. The Great , Mud , Flood and Shakes glaciers flow east and south, respectively, to the Stikine River. Overall, the glaciated area of the Stikine Icefield accounts for about 6% of the glaciated area of Alaska.
The global melting of glaciers is also visible at the Stikine Icefield: there has been a rapid loss of mass since the middle of the 20th century , which has accelerated since the turn of the millennium. In the lower consumption areas of the glaciers, their thickness decreases by up to 5 m per year.
The highest peak in the Stikine Icecap is Mount Ratz at 3090 m .
