Bolam Glacier, Mount Shasta Wilderness

The Bolam Glacier is a glacier situated on the northern flank of Mount Shasta, in the U.S. state of California. It is the second longest glacier in California behind the nearby Whitney Glacier, and the fourth largest and most voluminous after the neighboring Hotlum Glacier, Whitney Glacier, and Wintun Glacier. The Bolam Glacier flows from a cirque on the north side of Mount Shasta's main summit, with the moving ice starting below a large bergschrund which spans the glacier at 12,600 ft. Above that, permanent snow and ice extends towards the summit to about 13,500 ft. The glacier flows north down a steep slope and terminates near 9,800 ft. It has a contributing drainage area of 1.03 km². ()
