This surficial-geologic map shows the distribution of unconsolidated deposits and undifferentiated bedrock in the Faith Creek area in the Circle A-4, A-5, B-4, and B-5 quadrangles. This map was prepared principally by the interpretation of 1:63,360-scale, false-color, infrared aerial photographs taken in 1979 and 1981 and is locally verified by ground observations during field work in 2007.

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...

This map shows the distribution of unconsolidated deposits and undifferentiated bedrock exposed at the surface in the Sagavanirktok A-3, A-4, B-3, B-4, and portions of the Sagavanirktok A-5 and B-5 quadrangles. Units were mapped by interpretation of stereo pairs of approximately 1:65,000-scale false-color infrared aerial photographs taken in June and August 1978, as well as 2.5 m and 10 m resolution SPOT imagery collected in 2009 and 2010. Fieldwork was completed in 2008.

During 2006 and 2007 the Alaska Division of Geological & Geophysical Surveys conducted reconnaissance interpretive mapping of permafrost in Alaska Highway Corridor Segment 1, which straddles the Alaska Highway through the Tanana River valley from Delta Junction to the eastern boundary of the Mt. Hayes Quadrangle. Primarily, we inferred the extent of permafrost and ice content by interpreting ~1:63,360-scale, false-color infrared aerial photographs taken in August 1980.

This map illustrates the distribution of unconsolidated deposits and undifferentiated bedrcok units in the Salcha River-Pogo area.It was prepared by interpretation of 1:63,360-scale false-color infrared aerial photographs taken July 1978, July 1979, and August 1981, and is locally verified by ground observations during field visits.

The Alaska Division of Geological & Geophysical Surveys (DGGS) has conducted 1:63,360-scale geologic mapping of the Eagle A-1 Quadrangle. The area is part of the 100-year old Fortymile mining district and is located in eastern Alaska near the Alaska-Yukon border. This map illustrates potential near-surface sources of various geologic materials that may be useful for construction. Field observations indicate that each geologic unit (for example, stream alluvium) has a definite composition or range of composition. Therefore, the probable presence of materials is interpreted from the distribution of geologic units on the geologic map of this quadrangle. This map is generalized and is not intended to show exact locations...

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,...
