Mount Baker Glacier’s Perspective on Climate Change 1984-2022-Disastrous!
Camp above Coleman Glacier on Heliotrope Ridge, (Jill Pelto painting) Mount Baker is the most glaciated peak and highest mountain in the North Cascade Range at 3286 m. The Nooksack Indian Tribe refers to this strato volcano as Komo Kulshan, the great white (smoking) watcher. Mount Baker has 12 significant glaciers that covered 42 km2 in 1984 and ranged in elevation from 1320 m to 3250 m. Kulshan watches over …

Mount Baker Glaciers, Washington Snowpack Recession and Evolution May 2022-May 2023
Sholes Glacier snowcover extent change from 8-8-2022 to 10-17-2022. Snowcover declined from 98% of glacier to 10% of glacier during this period. Black dots are measurement sites, yellow dots the transient snowline, purple contour= 1.5 m, green contour= 2 m, brown contour= 2.5 m, and orange contour= 3 m snow depths on 8-8-2022. The 2022 melt season for Moutn Baker glaciers was one for the record books, with a slow …

Sholes Glacier, WA and a Cascade of Ologies
Watercolor painting of Sholes Glacier. The small figure is at the current terminus of the glacier, and the photo that inspired this painting was taken from where the glacier used to end about 35 years prior. By Jill Pelto Sholes Glacier is on the northeast flank of Mount Baker, WA. We have spent the last 32 years completing detailed measurments on this glacier that has revealed a story of glacier …

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 …

Art and Science on the Easton Glacier: Reflections from the NCGCP 2020 Field Season
By: Cal Waichler, Jill Pelto, and Mariama Dryak. It is the evening of Aug. 9th, 2020 and six of us are camped near the terminus of Easton Glacier. The sun has dropped below the moraine ridge above camp and a chilly breeze has forced us to put on layers. We are enjoying dinner cooked on our camp stoves, discussing what we observed on the ice today. The toll of climate …

34th Annual, 2017 North Cascade Glacier Climate Project Field Season
2017 Field Season Video For the thirty fourth consecutive summer we headed into the field to monitor the continued response of North Cascade glaciers to climate change. In 1984 when I began this program we selected 10 key glaciers to monitor. Two of these have now disappeared. All the glaciers have retreated extensively and lost considerable volume. The mass balance loss is 19 m of water equivalent thickness, which is over …

Climate Driven Retreat of Mount Baker Glaciers and Changing Water Resources
We have spent 300 nights in a tent just on this mountain collecting data from 1984-2015 in this study that the book documents. This post has the same title as a book released last month as part of the Springer Briefs in Climate Studies series. The nice thing about publishing research emerging from 30 years of field research in a book is that I had a chance to include 104 …

Mazama Glacier Retreat, North Cascades, Washington
Mazama Glacier flows down the north side of Mount Baker, a strato volcano in the North Cascades of Washington. The glacier begins at the summit plateau, 3260 meters, and terminates at the head of Wells Creek 1470 meters. This is a glacier we visit briefly each summer since 1984, but is not a focus of detailed observations. In 2010 we descended from its divide with Rainbow Glacier at 2100 meters …
