Exposed permafrost along the route of the trans Alaska oil pipeline is examined by a geologist employed by the line’s builders. Permafrost is defined as “unconsolidated deposits or bedrock that continuously have had a temperature below zero degrees Centigrade for two years or more.” In areas where the permafrost is “ice-rich,” the pipeline is elevated to avoid thawing the ground and thus losing support for the pipe., 1976 - 1977
Content Description
The collection contains both slides and photographs taken during the pipeline construction. Subjects include personnel, equipment, bridge construction, the winter environment, wildlife, pump stations, Port Valdez, the Haul Road and the terminal. There are several views of archaeologists from UAF working at the site. The 589 slides generally correspond to six typewritten progress reports, which begin in March 1976, when the pipeline was about 45% complete, and end in April 1977 at 95% completion. The remainder of the collection consists of 127, 8x10 in. black and white photographs.
