The National Park Service (NPS) conducted glacier surveys in Rocky Mountain National Park (RMNP), Colorado, beginning in 1932. This collection of glacier surveys covers the years 1932 to 1952. Most of the reports include several glacier photographs. Copies of the original reports are held in the NSIDC Analog Archives. You can access the entire reports using the listings below.
