Publication_Date: 200306 Title: Surficial geology of the Dalton Highway (Itkillik-Sagavanirktok rivers) area, southern Arctic foothills, Alaska Geospatial_Data_Presentation_Form: map and vector digital data Series_Information: Series_Name: Professional Report Issue_Identification: PR 121 Publication_Information: Publication_Place: Fairbanks, AK, USA Publisher: State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (DGGS) Other_Citation_Details: 32 p., 1 sheet, scale 1:63,360 Online_Linkage: http://dx.doi.org/10.14509/7191 Description: Abstract: This report provides detailed (1:63,360-scale) surficial-geologic mapping in the Dalton Highway area, from the Sagavanirktok to the Itkillik Rivers, in the west-central Philip Smith Mountains quadrangle. The map area extends from the northern flank of the Endicott Mountains into the Arctic Foothills province. Purpose: The surficial-geologic map from the Sagavanirktok to the Itkillik Rivers was selected by the Alaska Division of Geological & Geophysical Surveys (DGGS) for detailed (1:63,360-scale) mapping to document depositional relationships and the extent of surficial deposits near the Dalton Highway on the North Slope of Alaska. This map provides a comprehensive understanding of Northern Alaska glaciation. Detailed surficial mapping is an important first step in creating engineering-geologic maps to identify construction materials needed for maintenance and development of the infrastructure that connects and supports the North Slope oil fields. Supplemental_Information: The layers listed below are present as ArcGIS shape files. To enhance print quality, this publication utilized a vector topography data set (released as an add-on to the DGGS publication PIR 2002-2). 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. Each layer is listed and described in detail under its own heading starting "Entity_Type_Label." Basic unit information is also included in the geologic unit code set file "PR121_codeset.pdf".

Location data for geologic point coverages was acquired from hand held GPS units and compiled on paper field maps, air photos, and notebooks. A paper compilation map composed of all of the geologic information elements was scanned and digitized using a digitizing tablet. Spatial data attributes were attached to data objects using ArcInfo. Attributes were verified for consistency and completeness during the creation of the metadata. Logical_Consistency_Report: Topology is present on appropriate polygon and line data tables; others are point data tables. Completeness_Report: This data set includes coverages that contain information about geologic units, their ages, and field sample locations at 1:63,360 scale. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data and estimated position errors were manually entered into a spreadsheet. Sample numbers and locations with selected data were spatially registered and analyzed in ArcGIS software. Location data was determined visually using topographic maps at a scale of 1:63,360 and 1:50,000 (nominal) scale, color-infrared aerial photographs. See "Source_Information" section for horizontal positional accuracy of locations not measured by DGGS. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 10 Horizontal_Positional_Accuracy_Explanation: A value of estimated position error in meters was calculated by hand held GPS units and recorded for each sample location. Estimated position error calculated by the GPS units was not less than 3 meters and averaged approximately 6 meters. The GPS system suffers from calculation and geometric error. This error results from items such as error in satellite positions, mathematical error introduced by the formulas used by the GPS unit for calculating position, and errors caused by narrow satellite alignments. Estimated position error is a value determined by the GPS manufacturer for the calculation and geometric error as a whole. "Selective availability," a deliberate degradation of GPS data managed by the U.S. government that induces an additional error of approximately 100 meters to a GPS location, was not in effect during DGGS's 2001 field work. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 100 Horizontal_Positional_Accuracy_Explanation: A value of estimated position error in meters. Surficial geologic map data have a horizontal positional accuracy dependent on: 1) the 1:50,000-scale (nominal) aerial photographs on which it is based, with an estimated potential error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; 2) the accuracy of the human zoom transfer scope operator in tracing the line work from acetate overlays to topographic base maps, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; 3) the accuracy of the zoom transfer process itself, error magnitude highly variable and unknown but potentially large; 4) the digitizing RMS error of 0.003 inches (input coverage units), which equates to approximately 5 meters on the ground for a 1:63,360-scale map; and 5) the accuracy of the human operator digitizing the geologic from the topographic base maps, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground. The surficial field maps were digitized using a map tablet and cross-hair mouse. Map error is induced by: (1) transferring map data from base topography to a Mylar compilation map, with an estimated potential error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; (2) the digitizing RMS error [24 control points on a regular grid have an average RMS error of 10.8 meters on the ground; individual control point error ranges from 4.3 to 21.2 meters on the ground]; and (3) the accuracy of the human operator digitizing the geologic line work from the topographic base map, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground. Total potential horizontal error for geologic map features is estimated to be approximately 100 meters. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Brosgé, W.P.

Geologic map contacts were delineated by photo interpretation of 1:50,000-scale color-infrared aerial photographs onto clear acetate overlays. The contacts were transferred from the overlays onto paper USGS 1:63,360 topographic base maps using a zoom transfer scope, and the contacts were then digitized using ArcEdit. Line work was edited using ArcEdit, and polygon topology generated and unit designations assigned using ArcInfo and ArcEdit. ArcPlot was used to generate plot files using DGGS-standard symbology, and the Arc graphics files were converted into .eps files for export to Corel Draw for final cartographic assembly.
