Thirty-third Annual North Cascade Glacier Climate Project Field Season Underway

Base Map of the region showing main study glaciers, produced by Ben Pelto. From President Reagan to President Obama each August since 1984 I have headed to the North Cascade Range of Washington to measure the response of glaciers to climate change.  Specifically we will measure the mass balance of nine glaciers, runoff from three glaciers and map the terminus change on 12 glaciers. The data is reported to the …

Anderson Glacier, Olympic Mountains, Washington Disappears

Anderson Glacier was the headwaters of the Quinault River in the Olympic Mountains of Washington. A century ago the glacier was 2 km long, and a half kilometer wide. Retreat of this glacier in the first half of the 20th century exposed a new alpine lake as the glacier retreated 1 kilometer. From 1950-1980 the glacier diminished slowly. From 1959 to 1990 the glacier thinned and retreated from the shore …

Dusty Glacier, Glacier Peak, WA

In the 1990’s the North Cascade Glacier Climate Project undertook a study of all the glaciers around Glacier Peak, one century after they had been first observed by C.E. Rusk. This post focuses on one of those glaciers, Dusty Glacier on the Northeast side of the peak. In 1940 J.B. Richardson of the Forest Service photographed many North Cascade glaciers surrounding Glacier Peak. From 1946-1958 William Long, of the Forest …
