Summary

During 2008 the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted reconnaissance interpretive mapping of permafrost in Alaska Highway Corridor Segment 2, a 12-mi-wide (19.3-km-wide) corridor that straddles the Alaska Highway through the upper Tanana River valley from the eastern boundary of the Mt. Hayes Quadrangle to the eastern edge of the Tanacross Quadrangle. This work was an extension of permafrost mapping done in Alaska Highway Corridor Segment 1 from Delta Junction to Dot Lake in the Big Delta and Mt. Hayes Quadrangles during 2006-2007. Primarily, we inferred the extent of permafrost and ice content by interpreting ~1:65,000-scale, false-color infrared aerial photographs taken in July 1978, August 1980, and [...]

Purpose

This report and map are a part of ADGGS's Alaska Natural Gas Pipeline Geology and Geohazards project, funded by the state legislature, showing an interpretive evaluation of the presence or absence of permafrost in the study area. The study was done in anticipation of the proposed natural gas pipeline along the Alaska Highway corridor, as a preliminary look at the expected distribution of permafrost based on air photo interpretation. The work was designed to serve as the springboard for the detailed work which would be required if a pipeline were to be built along this corridor. Because of the dearth of subsurface data in most of the map area, our permafrost designations should be considered tentative until validated by multi-year ground-temperature measurements at a depth below the level of annual temperature variation.
