Mount Baker camp for Rainbow and Sholes Glacier (Illustration by Megan Pelto) Science Director: Mauri S. Pelto, [email protected] Art Director: Jill Pelto, [email protected] 2022 Field Season: For the 39th consecutive summer we are heading into the field to measure and communicate the impact of climate change on North Cascade glaciers. We will complete detailed measurements on 10 glaciers, three of which are part of the World Glacier Monitoring Service reference glacier network …

NORTH CASCADE GLACIER CLIMATE PROJECT 2020-37th Annual Field Program

Field season images from 2019 indicating crevasse stratigraphy, annotated by Clara Deck. Director: Mauri S. Pelto, [email protected] College Field Artist & Scientist: Jill Pelto, [email protected] Who we are? NCGCP was founded in 1983 to identify the response of North Cascade glaciers to regional climate change, particularly changes in mass balance, glacier runoff and terminus behavior.   NCGCP is a field project that has a broader interdisciplinary scope and examines more glaciers than any …

36th Annual North Cascade Glacier Climate Project Field Season Begins

Fieldwork includes terminus surveys, glacier runoff measurement and mass balance measurements Field Season Begins August 1 Who we are? The North Cascade Glacier Climate Project (NCGCP) was founded in 1983 to identify the response of North Cascade glaciers to regional climate change, particularly changes in mass balance, glacier runoff and terminus behavior.   This was prompted by the  National Academy of Sciences listing this as a high priority and a personal …

35th Annual Field Season Monitoring North Cascade Glaciers Preliminary Assessment

We monitor the response of North Cascade glacier to climate change and the consequent impacts for water resources and the ecosystem, as illustrated here by Megan Pelto and Jill Pelto. For the 35th consecutive year I headed to the North Cascade Range, Washington to monitor the response of glaciers to climate change. During the course of this study we  observed several of the glaciers we monitor disappear.  Two of the …

Looking Inside a Glacier

Here we provide a visual look inside a glacier in the North Cascades of Washington.  Glaciers are not all the same, but the key internal ingredients in summer typically are in varied ratios: ice, meltwater, sediment and biologic material.  In this case there are torrents of water pouring through the interior of the glacier, generated at the surface the day we are filming.  We do measure the discharge and velocity …

Disastrous Year for North Cascade Glacier Mass Balance (Snow/Ice Economy)

  Mass loss of North Cascade glaciers visualized. A disastrous year is unfolding in 2015 for North Cascade glaciers, if normal melt conditions continue the range will lose 5-7% of its entire glacier volume in one year! For the 32nd consecutive year we were in the North Cascade Range, of Washington to observe the mass balance of glaciers across the entire mountain range. The melt season is not over, but …

Embarking on the 32nd Annual North Cascade Glacier Climate Project

  Sholes Glacier snowcover Aug. 5, 2013 (Jill Pelto) and Sholes Glacier July 23, 2015 (Oliver Grah) For the 32nd straight summer we will be investigating North Cascade glaciers and their response to climate change over the next three weeks (that means no new posts until Aug. 20).  In 1984 the program was initiated to study the impacts of climate change across an entire mountain range, instead of on just one glacier. …

Sholes Glacier, Washington: Measuring Annual Glacier Mass Balance

Annual mass balance is the difference between ice and snow added to the glacier via accumulation and snow and ice lost via ablation and in some cases calving. Alpine glacier mass balance is the most accurate indicator of glacier response to climate and along with the worldwide retreat of alpine glaciers is one of the clearest signals of ongoing climate change (WGMS,2010). For 25 consecutive years we (North Cascade Glacier Climate …

28th Field Season of the North Cascade Glacier Climate Project 8-1 to 8-20

During the interval of 8-1 to 8-20 there will be no blog updates, we will be in the field for the entire period. This is the 28th consecutive year we will monitoring the terminus behavior and mass balance of these glaciers identifying how they respond to climate change. In these 28 years all the glaciers have retreated significantly they have lost 20% of their volume and two of the glaciers …

Rainbow Glacier Mass Balance

In 2010 at the end of a four day period of cool rainy weather we hiked into to our base camp on Ptarmigan Ridge to measure the mass balance of the Rainbow Glacier on Mount Baker in the North Cascades of Washington for the 27th consecutive year. Below is a view of Rainbow Glacier as we approach it. This is a valley glacier that begins on the slopes of Mount …

North Cascade Glacier Climate Project 27th field season 2010 starts Aug. 1

For the next three weeks I will be in the North Cascades of Washington visiting and measuring snowpack, snow melt and area change on North Cascade glaciers. There will be no new posts here during this period. Though you can take a look at the film documentary crews site travelling with us. Our main task is assessing glacier mass balance on 10 glaciers which are then reported to the World …
