Carson, E.C. 2009 map, vector digital data Report of Investigation RI 2009-3 Fairbanks, Alaska Alaska Division of Geological & Gephysical Surveys 1 sheet, scale 1:63,360 During the 2006 field season, the Alaska Division of Geological & Geophysical Surveys conducted remote mapping as part of the Kavik River STATEMAP project.This surficial-geologic mapping was conducted to provide additional detail to the STATEMAP comprehensive geologic mapping as well as to serve as a stand-alone map publication. This map is part of the Alaska Division of Geological and Geophysical Survey's Kavik River STATEMAP project in the Mount Michelson 1:250:000 Quadrangle. It provides a detailed overview of the surficial geology in the STATEMAP project area and will serve as a stand-alone publication (this publication). The resultant data will also be integrated into a subsequently released bedrock geologic map. The coverages included in this project are digitized from a mylar compilation of geologic field observations recorded on U.S. Geological Survey topographic base maps of the area and on aerial photos.Coverages were created using ArcMap distributed by ESRI, Inc.Metadata was compiled to meet Federal Geographic Data Committee standards.Digital hydrology and topography of the map area is included with this publication release but documented in a separate matadata file.This dataset includes 3 layers.Each layer is listed and described in the metadata under the headings "Entity_Type_Label."Layers include: >kavik_Q_units polygons representing geologic units >kavik_Q_structure line symbols representing structures >kavik_Q_contacts line symbols representing contacts between geologic units 2006 ground condition Complete None planned -147.00000 -146.00000 69.75000 69.25000 None Alluvial Deposits Geologic Map Glacial Deposits Surficial Geology None Brooks Range Canning River Mount Michelson Quadrangle None Itkillik Glaciation Sagavanirktok River Glaciation Anaktuvuk River Glaciation None Holocene Pleistocene Quaternary This report, map, and/or data set are available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys Any hardcopies or published data sets utilizing these data sets shall clearly indicate their source.

The author would like to thank the staff of the Alaska Division of Geological & Geophysical Surveys, including P.R. Delaney, R.J. Gillis, A.M. Loveland, R.R. Reifenstuhl, R.F. Swenson, M.A. Wartes; and W.K. Wallace of the University of Alaska Fairbanks. Technical Review by: D.S.P. Stevens (ADGGS) and D.F. Waythomas (U.S. Geological Survey); Digital Cartography by: A.M. Loveland (ADDGS); Edited by: P.K. Davis and P.R. Delaney (ADGGS) The attributes of this geospatial data set consist of text identifiers and numeric codes that indicate the identity of the geologic unit or type of geologic feature and determine how each feature is symbolized.To check attribute accuracy, a color check plot was visually compared to the geologist's original compilation. Discrepancies between the digital geospatial dataset and the original analog or digital compilation were corrected as needed. The geologic interpretations presented in this report have undergone two technical reviews by geologists familiar with the subject of the report or geology of the map area. Reviewers' suggestions were incorporated into the final draft when deemed appropriate by the author. Polygon topology is present and clean on appropriate coverages. The data set includes contact locations as observed in the field and distinguishable at a scale of 1:63,360. Contact locations and geologic unit distinctions where determined in the field using raster images of topographic base maps, aerial photos and handheld GPS units. Sources of possible error include the manual-visual proceedure used to resolve scale differences between the aerial photos and the topographic base maps and errors associated with digitization process. Inclusive of such errors, contacts are thought to be within 20-30 m of where they are mapped, with the exception of contacts which were specifically designated as "inferred."

The mylar was overlaid on the air photos and then frequently positioned based on prominent features visible on both air photo and map (primarily streams). In the field numerous soil excavations were conducted to verify sediment characteristics. Moraines (primarily the Itkillik I and Itkillik II moraines) were measured in the field for the following properties to aid identification: moraine crest height, moraine crest width, moraine slope angle, and depth of soil oxidation. Hamilton, 2003 Pinney, 2000 Waythomas, 1991 2006 Digital cartography - The mylar overlay was scanned and georeferenced using ArcMap 9.2. Map boundaries were digitized on-screen at a scale more detailed than 1:63,360, using a USGS topographic 1:63,360 map layer that was created in All Topo to verify position. Surficial geology map polygons and lines were then digitized and attributed using ArcMap 9.2. 2006 Universal Transverse Mercator 6 0.99960 -147.0 0.00001 500000.0 0.1 coordinate pair 0.00001 0.00001 meters kavik_Q_units Universal Transverse Mercator 6 0.9996 -147 0.00001 500000 0.1 coordinate pair 0.00001 0.00001 meters kavik_Q_structure Universal Transverse Mercator 6 0.9996 -147 0.00001 500000 0.1 coordinate pair 0.00001 0.00001 meters kavik_Q_contacts North American Datum of 1927 Clarke 1866 6378137 298.25722210088 kavik_Q_units kavik_Q_units.shp vector, represents geologic formations Alaska Division of Geological & Geophysical Surveys unit_name geologic unit Alaska Division of Geological & Geophysical Surveys Qa modern stream alluvium Alaska Division of Geological & Geophysical Surveys Qac abandoned channel deposits Alaska Division of Geological & Geophysical Surveys Qaf alluvial fan deposits Alaska Division of Geological & Geophysical Surveys Qat alluvial terrace deposits Alaska Division of Geological & Geophysical Surveys Qcc coarse-grained colluvium Alaska Division of Geological & Geophysical Surveys Qcf fine-grained colluvium Alaska Division of Geological & Geophysical Surveys Qls landslide deposits Alaska Division of Geological & Geophysical Surveys Qlt thaw lake deposits Alaska Division of Geological & Geophysical Surveys Qdi2 drift of Itkillik II age Alaska Division of Geological & Geophysical Surveys Qdi1 drift of Itkillik I age Alaska Division of Geological & Geophysical Surveys Qds drift of Sagavanirktok River age Alaska Division of Geological & Geophysical Surveys Qdos outwash of Sagavanirktok River age Alaska Division of Geological & Geophysical Surveys Qda drift of Anaktuvuk River age Alaska Division of Geological & Geophysical Surveys Qdu undifferentiated drift of Sagavanirktok and Anaktuvuk River age Alaska Division of Geological & Geophysical Surveys Qkt kame terrace Alaska Division of Geological & Geophysical Surveys Qsu silt, undifferentiated Alaska Division of Geological & Geophysical Surveys Qts thawed silt deposits Alaska Division of Geological & Geophysical Surveys kavik_Q_structure kavik_Q_structure.shp vector, represents geologic structures Alaska Division of Geological & Geophysical Surveys structure_type line, type of structure, determines symbology Alaska Division of Geological & Geophysical Surveys ridge_crest ridge crest Alaska Division of Geological & Geophysical Surveys ridge_crest_queried ridge crest, position queried Alaska Division of Geological & Geophysical Surveys scarp fault scarp Alaska Division of Geological & Geophysical Surveys kavik_Q_contacts kavik_Q_contacts.shp vector, represents contacts between geologic units Alaska Division of Geological & Geophysical Surveys contact_type type of contact, determines symbology Alaska Division of Geological & Geophysical Surveys inferred inferred contact Alaska Division of Geological & Geophysical Surveys Alaska Division of Geological & Geophysical Surveys mailing and physical
