As part of the 2016-17 Huxley College of the Environment Speaker Series, Dr. Jon Riedel will deliver his talk, “Blue Ice: Photographic and Scientific Evidence of the Recent Loss of Glaciers in Washington's National Parks,” at 4:00 p.m. on Thursday, February 23 in Miller Hall 138 on the Western Washington University campus. The presentation is free and open to the public.
The presentation will discuss the recent loss of glaciers in Washington’s National Parks. More than 500 glaciers grace the summits of Washington’s three National Parks. Aerial photographic evidence of their status was collected at various times in the last century, which has allowed for comparisons. Along with this data, scientific evidence of change in the parks’ glaciers includes recent estimates of change in glacial area for all glaciers and measurement of mass balance at eight glaciers in the national parks. These data were combined to assess changes in basin wide-volume and the glacial contribution to summer streamflow in several large watersheds around the southern Salish Sea.
Jon Riedel is a geologist with the U.S. National Park Service at North Cascades National Park, and holds a M.S. degree from the University of Wisconsin (1987) and a Ph.D. from Simon Fraser University (2007). For more than 30 years his research has focused on the sensitive response of Washington’s glaciers to climate change, from the last ice age 30,000 years ago to modern glaciers. Dr. Riedel’s recent research into the distant past has focused on glaciation of the valley and environmental conditions during the last ice age.
The presentation will include a question-and-answer period. Anyone interested in the topic is encouraged to attend and participate. For more information, please contact WWU’s Huxley College of the Environment at (360) 650-2554
