PHOTOS SOUGHT FOR GLACIER RESEARCH

Researchers at Portland State University are seeking photographs of alpine

glaciers in the Lower 48, particularly historic or current photos that show

the terminus (snout) of the glacier with the surrounding landscape in late

summer. Andrew Fountain of the university's Department of Geology, writes,

"We intend to compare photos of the same glacier, but taken over different

times, to infer the magnitude of glacier advance or retreat. This is part of

a project to assess glacier change over the past 100+ years. We will make

the data derived from the photos available to all using our web site:

www.glaciers.us." For more information or to make arrangements to deliver

photos, contact Fountain at Andrew@pdx.edu .

Portland State is cooperating with another fascinating collection of

historical glacier photographs at the National Snow and Ice Data

Center/World Data Center for Glaciology. These photographs are primarily of

Alaskan glaciers but also include the Pacific Northwest, the Rocky

Mountains, and Europe. Many of the photographs in this remarkable collection

have been digitized and can be viewed online. Go to

http://nsidc.org/data/glacier_photo/photo_query.html to check out your

favorite glacier.
