Loss of Glaciers in Washington's National Parks

For more than 30 years, Dr. Jon Riedel, a geologist with the National Park Service at North Cascades National Park, has researched the response of Washington’s glaciers to climate change, from the last ice age 30,000 years ago to modern glaciers. Jon established glacier monitoring programs at Olympic, Mount Rainier and North Cascades national parks to track changes in more than 500 glaciers. He will show images of glacial change, share results of the monitoring program, and conclude with an example of how the loss of glaciers affects summer streamflow.
