White Salmon Glacier

White Salmon Glacier lies on the southwest side of Mount Adams in Washington below the summit crater. It begins at about 11,600 feet and descends to a terminus near 9,600 feet, with part of its ice feeding Avalanche Glacier around 10,200 feet. Its modern significance is the scale of its retreat: from 1904 to 2006, it lost 86 percent of its surface area. This dramatic reduction makes it a clear example of the long-term shrinkage affecting the glaciers of Mount Adams.
