Title:
Engineering-geologic map of the Dalton Highway from Galbraith Lake to Slope Mountain, southern Arctic Foothills, Alaska
Abstract:
This derivative engineering-geologic map illustrates potential near-surface sources of various geologic materials that may be useful for construction near the Dalton Highway area, from Atigun Gorge to Slope Mountain. The map area is located in the west-central Philip Smith Mountains quadrangle. The map extends from the northern flank of the Endicott Mountains into the Arctic Foothills province. 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. Map unit descriptions also include discussion of the potential geologic hazards that can be inferred from the typical physical properties of each map unit, such as sediment texture and ground-ice content and typical topographic settings. This map is generalized and is not intended to show exact locations of specific materials. Local variations are common, especially near unit boundaries. The map was derived electronically from a related surficial geologic map of the area using Geographic Information System (GIS) software. Geologic units were locally verified by ground observations during field visits. The results should be considered reconnaissance in nature.
Supplemental_Information:
The DGGS metadata standard extends the FGDC standard to include elements that are required to facilitate our internal data management. These elements, referred to as "layers," group and describe files that have intrinsic logical or topological relationships and correspond to subdirectories within the data distribution package. The metadata layer provides an FGDC metadata file and may include other documentation files. Attribute information for each data layer is described in this metadata file under the "Entity_and_Attribute_Information" section. Data layer contents:
border:    A polygon that encompasses the maximum geographic extent of the data observations
MapUnitPolys:    Polygons that record the distribution of mapped or interpreted geologic units
OtherPolys:    Polygons that record the location and extent of geologic or geographic features other than the geologic units.

  2. How were the data generated, processed, and modified?

    Date: 2002 (process 1 of 2)
    Engineering unit interpretation - Surficial-geologic units were initially identified by interpretation of ~1:65,000-scale false-color infrared aerial photographs (1979 and 1982) and locally verified by field checking (2001). Geologic units and other data from the surficial geologic map of the area were subsequently used as the basis for generating the derivative engineering-geologic map. We interpreted the physical properties of the surficial-geologic units based on extrapolation from verified localities and from previously published reports and data. We inferred the potential geologic hazards from the typical physical properties of map units, including sediment texture and ground-ice content, and their typical topographic settings.

    Data sources used in this process:

    • Harris, E.E. and others, 2002
    • Hamilton, T.D., 2003
    • American Society for Testing and Materials, 1998

    Date: 2013 (process 2 of 2)
    GIS analysis and digital cartography - The geologic and geographic features portrayed on this may were derived electronically from the surficial-geologic map of the area using Geographic Information System (GIS) software. Surficial geologic units were grouped based on common properties that are typically significant for engineering applications. Polygons were attributed according to the NCGMP09 geodatabase standard. Topographic basemaps: Phillip Smith Mountains B-4, B-5, C-4, C-5, D-4 (published in 1971 - minor revisions 1975).

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Engineering-geologic map units were derived from the surficial-geologic map. Physical properties of engineering-geologic map units are interpretive, based on extrapolation from verified localities and from previously published reports and data. Certainty in identification of the map units varies due to the scale and interpretive nature of the mapping. The geologic unit interpretations and boundaries presented in this report result from interpretation of aerial photographs as well as investigative traverses throughout the map area, aerial reconnaissance via helicopter, and examination of road-cuts and river exposures. 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 used 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. This map has received two technical reviews by geologists familiar with the subject matter. We incorporated the reviewers' suggestions into the final draft.

  2. How accurate are the geographic locations?

    All boundaries are inferred or approximately located. Surficial-geologic units were initially identified by interpretation of ~1:65,000-scale false-color infrared aerial photographs (1979 and 1982) and locally verified by field checking (2001). We believe the total horizontal accuracy of the mapped surficial-geologic contacts is on the order of 25 m or better, with somewhat lesser accuracy expected in areas of rugged relief.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    This dataset includes shapefiles that contain information about the mapped and interpreted engineering-geologic deposits in the map area distinguishable at a scale of 1:63,360. No analytical tests were conducted for this report. The table describes engineering properties 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.

  5. How consistent are the relationships among the observations, including topology?

    Polygon topology was present and clean on the original ArcGIS geodatabase. All polygon features were topologically validated using ArcGIS prior to export to shapefile format.
