Reger, R.D. Solie, D.N. 200812 Engineering-geologic map, Alaska Highway corridor, Delta Junction to Dot Lake, Alaska vector digital data Preliminary Interpretive Report PIR 2008-3B Fairbanks, Alaska - USA State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys 2 sheets, scale 1:63,360 http://www.dggs.dnr.state.ak.us/pubs/pubs?reqtype=citation&ID=17981 The engineering-geologic map, on two sheets, is derived electronically from the surficial-geologic map of the initial segment of the proposed natural gas pipeline corridor through the upper Tanana valley (Reger and others, PIR 2008-3a) using Geographic Information System (GIS) software. Surficial-geologic units were initially identified by interpretation of false-color ~1:63,000-scale infrared aerial photographs taken in July 1978, August 1980, and August 1981 and locally verified by field checking in 2006 and 2007. The map shows the distribution of surficial-geologic and bedrock units grouped genetically with common properties that are typically significant for engineering applications. This map is a part of ADGGS's Alaska Natural Gas Pipeline Geology and Geohazards project, mapping the geology, geohazards and resources along the the Alaska Highway between Delta Junction and Dot Lake. The study was done in anticipation of the proposed natural gas pipeline along the Alaska Highway corridor, to further the geologic understanding of the area andas a basis for evaluating geohazards and resources for proposed infrastructure. The layers listed below are present as ArcGIS shape files. To enhance print quality, this publication utilized a vector topography data set. The topography data set is not included with this release. Attribute information for the following layers (entities) is included in this metadata file under the "Entity_and_Attribute_Information" section. A codeset file titled, PIR2008-3B_codeset.pdf, contains the table explaining the properties of each engineering-geologic unit. There are two layers. Each layer is listed and described in detail under its own heading starting "Entity_Type_Label.

Engineering-geologic map units were derived from the surficial-geologic map (PIR 2008-3A). Physical properties of engineering-geologic map units are interpretive, based on extrapolation from verified localities and from previously published reports and data. Potential geologic hazards are inferred from the typical physical properties of map units, including sediment texture and ground-ice content, and their typical topographic settings. Except for a few test pits, no subsurface investigations or laboratory analyses were performed for this publication. The reader is cautioned that this map is intended only as a general guide, and that unevaluated geologic resources and hazards may be present. Detailed geotechnical investigations should be conducted prior to utilization of any map units for engineering purposes. Polygon topology is present on appropriate coverages This dataset includes coverages that contain information about the mapped and interpreted engineering-geologic deposits in the map area. Subsurface data were not available for use in creating this map coverage, other than about 10-15 soil pits dug to depths no more than 1.3 m, observations of exposures in gravel pits, highway cuts, and river banks, and drillhole data from geotechnical reports written by the Department of Transportation and Public Facilities for highway construction projects. No analytical tests were conducted for this report. The table describes engineering propoerties that are generally present in the mapped surficial deposits, but local variations and exceptions are most certainly to be expected. The reader is therefore cautioned that this map is intended only as a general guide, and that unevaluated geologic resources and hazards may be present. Detailed geotechnical investigations should be conducted prior to utilization of any map units for engineering purposes. The engineering-geologic map units were derived from the surficial-geologic map (PIR 2008-3A). The surficial-geologic map contacts were first hand-drawn, using a magnifying stereoscope, onto acetate overlays registered to 1:50,000-scale (nominal) prints of digital aerial photographs. The horizontal accuracy of the map unit boundary locations varies due to the scale and interpretive nature of the mapping, but is expected to be accurate to at least 15 m. The 400dpi digital air photos were orthorectified using OrthoMapper 3.6 with an RMS error generally constrained to be less than 4 pixels, equating to approximately 20 m on the ground, although some areas with rugged terrain have larger errors. The individual orthophotos were mosaicked using Erdas Imagine 9.2 and ArcGIS 9. The acetate overlays were individually scanned and orthorectified using OrthoMapper based on the same equations developed for generating the orthophotos. Map unit boundaries were digitized on-screen into ArcGIS from the orthorectified overlays at a scale of approximately 1:25,000, using a combination of a digital USGS topographic 1:63,360-scale map layer (DRG) and the orthophoto mosaic layer to verify the position of the lines. Total horizontal accuracy of the mapped surficial-geologic contacts is thus on the order of 25 m or better, with somewhat lesser accuracy expected in areas of rugged relief. 25 mapped engineering-geologic contacts Kreig, R.A.
