Boulder Glacier Retreat, Mount Baker

Boulder Glacier flows down the west side of Mount Baker a strato volcano in the North Cascades of Washington. This steep glacier responds quickly to climate change and after retreating more than 2 kilometers from its Little Ice Age Maximum, it began to advance in the 1950’s as observed by William Long. The glacier advance had ceased by 1979. From 1988-2008 we (NCGCP) have visited this glacier at least every …

26th Annual North Cascade Glacier Climate Project 2009 Field Season

This video examines the 2009 North Cascade Glacier Climate Project Field Season. It is a look more at where we work, than what we find. Mass balances were substantial averaging -1.93 m. The winter season was wetter than average, with close to average snowpack in the North Cascades. Summer melt conditions were exceptionally warm, leading to enhanced melting and considerable losses in glacier volume. The mass loss of approximately 2 …
