Deming Glacier Icefall Deceleration 2017-2022 Driven by Mass Balance Loss
Deming Glacier velocity from NASA MEaSUREs ITS_Live at four locations from below icefall at blue X to above icefall at red X. There is not a significant change in velocity above the icefall (red X), but significant deceleration in the icefall and below the icefall. The Deming Glacier drains the southwest side of the summit of Mount Baker a stratovolcano in the North Cascades of Washington, with a massive icefall …

Observing Glacier Runoff Changes Under the Same Weather Conditions
View of Sholes Glacier on August 8th in 2015 left and 2017 right. Note difference in ratio of snow surface to ice surface exposed. Sholes Glacier is at the headwaters of Wells Creek in North Fork Nooksack River watershed in Washington. We have been measuring the mass balance of this glacier annually since 1990 and runoff in detail since 2012 (Pelto, 2015). Glacier runoff in this watershed during late summer …

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 …
