North Cascade Glacier Climate Project 2019, 36th Annual Assessment

 The summer of 2019 found the North Cascade Glacier Climate Project in the field for the 36th consecutive summer monitoring the response of North Cascade glaciers to climate change.  This long term monitoring program was initiated partly in response to a challenge in 1983 from Stephen Schneider to begin monitoring glacier systems before and as climate change became a dominant variable in their behavior. The field team was comprised …

35th Annual Field Observations of North Cascade Glaciers

The 2018 field season observations, conditions and summary. Field team Mariama Dryak, Erin McConnell, Jill Pelto and Mauri Pelto. For the 35th consecutive year I headed to the North Cascade Range, Washington to monitor the response of glaciers to climate change.  Two of the glaciers the North Cascade Glacier Climate Project (NCGCP) monitors are now part of the 42 glaciers comprising the World Glacier Monitoring Service  (WGMS) reference glacier network, …

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 …

34th Annual Field Program NORTH CASCADE GLACIER CLIMATE PROJECT 2017

  2016 Field Season Video NORTH CASCADE GLACIER CLIMATE PROJECT 2017 For the thirty fourth consecutive summer it is time to head 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 …

2016 Field Season Results-North Cascade Glacier Climate Project

For Mount Baker, Washington the freezing level from January-April 20 was not as high as the record from 2015, but still was 400 m above the long term mean. April 1 snowpack at the key long term sites in the North Cascades was 8% above average. A warm spring altered this, with April being the warmest on record. The three-four weeks ahead of normal on June 10th, but three weeks …

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 …

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 …

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 …

Nooksack River: Glacier Runoff Maintains Suitable Aquatic Conditions for Salmon

Illustration from Megan Pelto above left Sholes Glacier from our runoff measurement station above right. Glaciers are a critical water resource in the North Cascades of Washington for hydropower, irrigation , municipal supply and aquatic life. In dry summers glaciers play an even larger role in the overall water budget and maintaining suitable aquatic conditions.  The summer of 2015 will pose particular challenges due to the drought emergency that is likely to …

Rainbow Glacier: Record Ablation in 2014 for 1984-2014 Period

From 1984-2014 we have monitored the mass balance of the Rainbow Glacier on Mount Baker, North Cascade Range, Washington. This entails detailed monitoring of snowpack depth in July and August, and subsequent ablation to the end of the melt season. On July 13th the glacier was completely snowcovered. By August 10th the snowline had risen to 1575 m, with 1.4 m of ablation since July 13th. We measured the snowdepth …
