What does this data set describe?

Title:
Surficial-geologic map, Alaska Highway corridor, Delta Junction to Dot Lake, Alaska
Abstract:
During 2006 and 2007 the Alaska Division of Geological & Geophysical Surveys conducted reconnaissance surficial-geologic mapping in segment 1 of the Alaska Highway corridor, which straddles the Alaska Highway through the Tanana River valley from Delta Junction to the eastern boundary of the Mt. Hayes Quadrangle. Surficial-geologic deposits were initially mapped by interpreting ~1:63,360-scale, false-color infrared aerial photographs taken in August 1980 and field verified in 2006-2007.

Who produced the data set?

  1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)

  2. Who also contributed to the data set?

    This research was supported by Alaska State Capital Improvement Projects funding.Additional Acknowledgments: Mapping of surficial geology in the vicinity of the Clearwater Lake escarpment and its intersection with the trans-Alaska oil pipeline was accomplished in the mid 1970s in collaboration with Alyeska Pipeline Service Company, who released a report that includes data on near-surface stratigraphy and radiocarbon dates and provides evidence that the Clearwater Lake escarpment is not fault related (Alyeska Pipeline Service Company, 1976). We gratefully acknowledge the cooperation provided by Mike Metz and Alyeska. We also appreciate the logistical support and interest of Steve Squires and the rest of the Dry Creek community, who supplied us with fresh vegetables, excellent drinking water, and the log of their water well. Several other colleagues have collaborated in our study of this initial segment of the proposed pipeline corridor. Gary Carver brought his outstanding expertise in neotectonics of the central and eastern Alaska Range to the DGGS effort and provided enthusiastic leadership during the fault-trenching program. Tom Hamilton provided his unpublished report on the glacial history of the area and graciously allowed us to release his unpublished radiocarbon dates from the Gerstle River, Little Gerstle River, and Johnson River drainages. Tom Ager provided early black-and-white aerial photographs and discussed his interpretation of climatic changes in the corridor. Field visits with Dave Carter, John Galloway, and Florence Weber examined evidence of the oldest known glaciation in the corridor and first alerted us to the possibility of massive outburst flooding. Santosh Panda accompanied us into the field on numerous occasions and provided preliminary unpublished information on permafrost in the corridor. We thank the other members of the DGGS field crew, especially Kyle Obermiller and Sharon Hansen, for their support in the field and office, and Tom Ratledge for flying us safely in and out of all those tight places. Rod Combellick graciously reviewed this report and provided helpful comments that improved our presentation.

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

    Date: 2007 (process 1 of 5)
    Aerial photograph interpretation- Stereo pairs of ~1:63,360-scale, false-color infrared aerial photographs taken in August 1980 were used to initially map the surficial geology. Unit boundaries were drawn by hand onto acetate overlays, using a magnifying stereoscope. Overlays were registered to aerial photos using tick marks on the photos. Digital aerial photos and scanned overlays were individually orthorectified using Orthomapper 3.6.

    Data sources used in this process:

    • Krieg and Reger, 1976
    • Kreig and Reger, 1982
    • Carter and Galloway, 1978
    • Holmes, 1965

    Date: 2008 (process 2 of 5)
    Digital cartography- The acetate overlays were then individually scanned and orthorectified, using Orthomapper, v. 3.6, and georeferenced. The air-photos were orthorectified, photomosaiced and georeferenced. Map unit boundaries were digitized on-screen into ArcGIS from the orthorectified overlays at a scale more detailed than 1:63,360, using a combination of a USGS topographic 1:63.360 map layer and the orthophotomosaic layer to verify the position of the lines.Surficial geology map polygons and lines were then edited and attributed using ArcMap 9.0.

    Date: 2007 (process 3 of 5)
    Fieldwork - Reconnaissance field work was done in September 2006, during which observations were recorded for use during aerial photograph interpretation. In July-August 2007, field work to verify aerial photograph interpretations was performed. In addition to observations from ground traverses, several soil pits were dug using shovels to maximum depth of 1.3 meters to observe soil profiles, and observations of exposures along river banks and highway cuts were recorded.

    Data sources used in this process:

    • Pewe and Reger, 1983
    • Carver and others, 2008
    • Duk-Rodkin and others, 2004
    • Hamilton, 1994
    • Mason and Beget, 1991
    • Muhs and others, 2003
    • Pewe, 1975
    • Weber, 1986

    Date: 2008 (process 4 of 5)
    Metadata creation - Metadata were assembled by D.N. Solie to FGDC Standards using Metavist 1.2, DGGS 7.05, a data entry program for FGDC metadata with XML output.

    Date: 1969 (process 5 of 5)
    radiocarbon_data - radiocarbon samples were collected by Thomas D. Hamilton during fieldwork in 1969 and analyzed in the 1970's by Geochron Laboratories. Analytical details are not known.

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

  1. How well have the observations been checked?

    Initial reconnaissance field observations were made in 2006, after which surficial geology air-photo interpretations were done. Contacts were hand-drawn, using a magnifying stereoscope, onto acetate air-photo overlays at the scale of the air-photos (approximately inch-to-the-mile). The air-photos were taken in August 1980. During summer field work in 2007, map units were described, samples collected for analysis, and a limited number of test pits was dug. The accuracy of the map unit boundary locations vary due to the scale and interpretive nature of the mapping, but are expected to be accurate to at least 50 ft. Map units labeled with a "?" are considered to have an uncertain assignation. Information from previous geologic reports was incorporated during the interpretation process.

  2. How accurate are the geographic locations?

    The surficial geology was 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.Coordinates of soil pits and other field sites that are discussed in the text were recorded using a Garmin GPS model 76CSx with a horizontal error of 4 meters or less. Radiocarbon sample localities on sheets 1 and 2 were located by visual transfer of points from hand-drawn figures (T.D. Hamilton, unpublished) and should be considered estimated locations with an accuracy of approximately 120 m or better.

  3. How accurate are the heights or depths?

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

    This dataset includes coverages that contain information about the mapped and interpreted surficial-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 and observations of exposures in gravel pits, highway cuts, and river banks. Soil colors were described using the Munsell soil color charts. The Wentworth scale was used for grain size classification. Soil horizon descriptions in the map area used the U.S. Soil Conservation Service soil taxonomy (Soil Survey Staff, 1975). The radiocarbon analyses shown on Table 2, from T.D. Hamilton (unpublished), were run by Geochron Laboratories in the 1970's. Specific analytical procedures were not reported. The active faults shown on sheets 1 and 2 are more fully described in ADGGS Preliminary Interpretive Report 2008-3d by Carver and others (2008).

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

    Polygon topology is present on appropriate coverages; others are line or point coverages.
