Kennicott Glacier, White ice mass in Wrangell-St. Elias National Park, Alaska

Kennicott Glacier is a 35 km valley glacier in the Wrangell Mountains, flowing south-southeast from between Mount Blackburn and the Atna Peaks to end near McCarthy at about 450 m. Its main tributaries, the Gates and Root glaciers, join from the left. Meltwater leaves via the 8 km Kennicott River to the Nizina River.

A geologist with the U.S. Geological Survey named this glacier in 1899 to honor Robert Kennicott, who led scientific operations for a major expedition in the region. This naming reflects the early exploration efforts that brought attention to this remote area.

The glacier ends near McCarthy, and its meltwater feeds the 8 km Kennicott River down to the Nizina River. The glacier also gives its name to the M/V Kennicott, a vessel of the Alaska Marine Highway. The name honors Robert Kennicott, who led the scientific corps of the Western Union Telegraph Expedition in 1865.

Summer is the best time to visit when the road is passable and weather stays stable. Warm clothing and sturdy footwear are important even in warm months because proximity to the ice keeps temperatures cool.

Packsaddle Island is a nunatak, a rock peak that pierces the ice near the base of Mount Blackburn. The glacier also gave its name to the M/V Kennicott, a vessel of the Alaska Marine Highway.
