A Tale of Two Glaciers Columbia and Easton Glacier 2021

Terminus of Columbia Glacier on left with 1984 terminus location noted.  Observe the avalanche fans (A) and the relatively high snowcover on 8-2-2021.  At right is Easton Glacier on 8-11-2021 with the location of the 1990 terminus indicated, 440 m of retreat to the 2021 terminus position. The glacier has only 38% snowcover at this time, which is better illustrated below. Columbia and Easton Glacier in the North Cascade Range …

Easton Glacier Assessment, Washington

In August we will be making a detailed study of the Easton Glacier for the 23rd consecutive summer. Our main focus is measurement of snow depth and snow melt on the glacier. We will be mapping the terminus position and two profiles of the surface elevation across the glaciers at 1800 m and 1950 m. We will also examine two new bedrock knobs that have melted out in the midst …
