Summary

During 2009 the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted reconnaissance interpretive mapping of permafrost in Alaska Highway Corridor Segment 3, a 12-mi-wide (19.3-km-wide) corridor that straddles the Alaska Highway through the Northway-Tanacross Lowland and the southern Yukon-Tanana Upland from Tetlin Junction to the Canada border. 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 and Alaska Highway Corridor Segment 2 from the Robertson River to Tetlin Junction in the Tanacross Quadrangles during 2008. Primarily, we inferred the extent of permafrost and ice content by interpreting [...]

Purpose

This report and map are a part of ADGGS's Alaska Natural Gas Pipeline Geology and Geohazards project, funded by the state legislature. They show 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.
