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 …

Visualizing Glacier Melt Impacts

Key questions emerge from the summer of 2015 in the Pacific Northwest glacier basins. That can both be visualized and quantified. With record temperatures and minimum flows in most rivers in the Cascade Range during July and August of 2015, a key question was how much did glaciers contribute in basins that are glaciated?  Note the water pouring off the glacier and the lack of snowcover in the first few …

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. …

Colonial Glacier Retreat and Hydropower

Colonial Glacier is on the southwest side of Colonial Peak in the Skagit River Watershed, North Cascades of Washington. The North Cascade Glacier Climate Project has made six visits to this glacier over the last 25 years. Meltwater from this glacier enters Diablo Lake above Diablo Dam and then flows through Gorge Lake and Gorge Dam. These two Seattle City Light hydropower projects yield 360 MW of power. As this …
