Jon Riedel was born in central Wisconsin and first came to the Pacific Northwest as a volunteer in 1980.
For most of the past 30 years, he has studied the glaciers and the record of climate changes they have left in the North Cascades. Jon’s Master of Science research at the University of Wisconsin examined evidence of glacier fluctuations during the past 1,000 years.
In 1993, as geologist at North Cascades National Park, he instituted a program to monitor the annual mass balance of four glaciers. In 2003, he added monitoring of the Emmons and Nisqually glaciers at Mount Rainier and in 2014 began to monitor Blue and Eel glaciers at Olympic National Park.
In 2007, Jon completed his Ph.D. thesis at Simon Fraser University: “Late Pleistocene Glacial and Environmental History of Skagit Valley.” This research focused on glacial advances and environmental conditions during the last ice age between about 30,000 and 11,500 years ago.
Current research interests include the Holocene glacial records on Mount Rainier and Mount Baker and the impact of rapid glacial recession on stream temperatures and stream flow in the Skagit River Basin.
