North Cascade Glacier 2022 Initial Observations-39th Field Season

2022 North Cascade Glacier Climate Project Field Team Science Director: Mauri S. Pelto, [email protected] Art Director: Jill Pelto, [email protected] For the 39th consecutive summer we were in the field to measure and communicate the impact of climate change on North Cascade glaciers. We completed detailed measurements on 10 glaciers, three of which are part of the World Glacier Monitoring Service reference glacier network (42 glaciers globally), which have 30+ consecutive years of …

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 …

Easton Glacier, Mount Baker, WA Annual Retreat & Mass Loss 1990-2017

Mass balance, terminus and supra glacial stream assessment are illustrated in the video, Filmed by Mauri Pelto, Jill Pelto, Melanie Gajewski, with music from Scott Powers. This is the story of  the annual monitoring of Easton Glacier, Washington.  We have been monitoring Easton Glacier on Mount Baker, a stratovolcano in the North Cascade Range, Washington since 1990.  Each year we survey the terminus position, measure its mass balance, assess crevasse depths …

Conducting Long Term Annual Glacier Monitoring

Easton Glacier in 1990, 2003 and 2015 from same location. Below Painting by Jill Pelto of crevasse assessment using a camline. This is the story of how you develop and conduct a long term glacier monitoring program.  We have been monitoring the annual mass balance of Easton Glacier on Mount Baker, a stratovolcano in the North Cascade Range, Washington since 1990.  This is one of nine glaciers we are continuing to …

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 …

Mass Balance of the Easton Glacier 2009

Immediately below is Easton Glacier on Mt. Baker in the North Cascades in late May 2009. The glacier is still completely snow covered. The bench where the small gray cloud shadows are at 6000 feet averages 20 feet of snow remaining. Easton Glacier extends from the terminus at 5600 feet to the slopes near Sherman Crater at 9000 feet. Each summer since 1990 NCGCP has measured the mass balance of …
