The study area is a 12-mi-wide (19.3-km-wide) area that straddles the Alaska Highway from the western boundaries of the Tanacross B-3 and A-3 quadrangles near Tetlin Junction eastward to the eastern boundaries of the Nabesna D-1 and C-1 quadrangles along the Canada border. Mapping during 2008-2009 in the Tanacross and Nabesna quadrangles linked with the mapping completed in the Tanacross, Big Delta and Mt. Hayes quadrangles in 2006-2008. Surficial geology was initially mapped in this third corridor segment by interpreting ~1:65,000-scale, false-color, infrared aerial photographs taken in July 1978 and August 1981 and plotting unit boundaries on acetate overlays. Verification of photo mapping was accomplished during the 2008 and 2009 summer field seasons, when map units were described, soil pits were hand dug, and samples were collected for analyses. Purpose: The Alaska Division of Geological & Geophysical Surveys conducted this project, funded by the state legislature, to evaluate the geology, geohazard and material resources along the Alaska Highway corridor from Delta Junction to the Canada border. This was in preparation for a proposed natural gas pipeline, so that a baseline of geologic data would be publicly available upon which preliminary decisions could be made. The work was designed to serve as the springboard for the detailed work which would be required if a pipeline were to be built along this corridor. Supplemental_Information: Unit information and descriptions are included on each map sheet. 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. Attribute information for the layers (entity) is included in this metadata file under the "Entity_and_Attribute_Information" section. The layers are titled: >surf-geology: polygons of surficial-geologic map units >border: outline shape of the study area >localities: location of soil pits, radiocarbon samples, fossil localities, soil moisture localities, tephra locality, and ventifact site discussed in text Time_Period_of_Content: Time_Period_Information: Multiple_Dates/Times: Single_Date/Time: Calendar_Date: 1978 Single_Date/Time: Calendar_Date: 1981 Single_Date/Time: Calendar_Date: 2008 Single_Date/Time: Calendar_Date: 2009 Single_Date/Time: Calendar_Date: 2010 Single_Date/Time: Calendar_Date: 2011 Single_Date/Time: Calendar_Date: 2012 Currentness_Reference: ground condition Status: Progress: Complete Maintenance_and_Update_Frequency: Unknown Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -142.5 East_Bounding_Coordinate: -141 North_Bounding_Coordinate: 63.378 South_Bounding_Coordinate: 62.529 Keywords: Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: geoscientificInformation Theme: Theme_Keyword_Thesaurus: Alaska Division of Geological & Geophysical Surveys Theme_Keyword: Dunes Theme_Keyword: Eolian Theme_Keyword: Geologic Hazards Theme_Keyword: Geologic Map Theme_Keyword: Geologic Materials Theme_Keyword: Geological Process Theme_Keyword: Geology Theme_Keyword: Geomorphology Theme_Keyword: Proposed Natural Gas Pipeline Theme_Keyword: Remote Sensing Theme_Keyword: Surficial Geology Theme_Keyword: Surficial Theme_Keyword: Transportation Corridor Theme_Keyword: Unconsolidated Deposits Place: Place_Keyword_Thesaurus: Alaska Division of Geological & Geophysical Surveys Place_Keyword: Alaska Highway Corridor Place_Keyword: Alaska Range Place_Keyword: Alaska, State of Place_Keyword: Tanacross Place_Keyword: Tanacross Quadrangle Place_Keyword: Nabesna Place_Keyword: Nabesna Quadrangle Place_Keyword: Tetlin Junction Place_Keyword: Canada Place_Keyword: Midway Lake Place_Keyword: Tetlin National Wildlife Refuge Place_Keyword: Beaver Creek Place_Keyword: Scottie Creek Place_Keyword: Tanana River Place_Keyword: Nabesna River Place_Keyword: Chisana River Place_Keyword: Northway Place_Keyword: Northway Junction Stratum: Stratum_Keyword_Thesaurus: Alaska Division of Geological & Geophysical Surveys Stratum_Keyword: Delta Glaciation Stratum_Keyword: Donnelly Glaciation Temporal: Temporal_Keyword_Thesaurus: Alaska Division of Geological & Geophysical Surveys Temporal_Keyword: Pleistocene Temporal_Keyword: Quaternary Temporal_Keyword: Holocene Access_Constraints: This report, map, and/or dataset is available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: 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). Sediment samples were collected for sieve analysis and radiocarbon age dating. Analytical data described above were utilized in developing the geologic interpretations presented in this report. 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. To check attribute accuracy of the digital files we visually compared the original compilation against test plots of the files and corrected discrepancies between the digital geospatial dataset and the original analog as needed. The geologic interpretations presented in this report have undergone technical review by a geologist familiar with the subject of the report and the geology of the map area. We incorporated the reviewer's suggestions into the final draft when deemed appropriate. Logical_Consistency_Report: Polygon topology is present and clean on the original geospatial dataset. All polygon features were topologically validated using the ESRI ArcGIS 10 software prior to export to shape file format. The logical consistency of the point files has been visually checked but not systematically verified. Completeness_Report: This dataset includes shapefiles that contain information about surficial geologic units mapped in this area. This dataset utilizes field observations and air photo interpretations. It includes geospatial information about units traceable on air photos at a scale of ~1:65000 and/or in the field. The dataset displays: surficial geologic units and contacts, inferred geologic contacts, and point localities discussed in the text. Subsurface data available for this investigation includes about ~15 soil pits dug to depths no more than 1.3 m and observations of exposures in gravel pits, highway cuts, and river bank exposures. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The surficial interpretations were first hand-drawn, using a magnifying stereoscope, onto acetate air-photo overlays at the scale of the air-photos (approximately inch to the mile). The accuracy of the map unit boundary locations varies due to the scale and interpretive nature of the mapping and pen line width of approximately 0.001 meters which is equivalent to approximately 1.5 meters on the ground. The hand drawn map unit boundaries are expected to be accurate to at least 15 meters. Following interpretation, acetate overlays were then individually scanned, orthorectified and georeferenced using Orthomapper, v. 3.6. The air-photos were orthorectified, photo-mosaiced and georeferenced. Surficial 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 air-photo photomosaic layer to verify the position of the lines and points. Map error is induced by: (1) Scanning and orthorectifying air photos and overlays. The digitizing RMS error is 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. 2) On-screen digitizing from orthorectified overlays. The accuracy of the human operator digitizing polylines and point localities is related to the accuracy of interpretations from the orthorectified photos and overlays. 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, radiocarbon sampling localities, and other field sites that are discussed in the text were recorded using a Garmin GPS model 76CSx with an estimated precision generally less than 10 meters.

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.

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+ Source_Used_Citation_Abbreviation: USGS Tanacross A-1, 1952 - minor revisions 1971 Source_Used_Citation_Abbreviation: USGS Tanacross A-2, 1955 - minor revisions 1972 Source_Used_Citation_Abbreviation: USGS Tanacross A-3, 1948 - minor revisions 1978 Source_Used_Citation_Abbreviation: USGS Tanacross B-3, 1949 - minor revisions 1964 Source_Used_Citation_Abbreviation: USGS Nabesna C-1, 1955 - minor revisions 1963 Source_Used_Citation_Abbreviation: USGS Nabesna D-1, 1952 - minor revisions 1967 Source_Used_Citation_Abbreviation: USGS Nabesna D-2, 1955 - minor revisions 1978 Source_Used_Citation_Abbreviation: USGS Nabesna D-3, 1955 - minor revisions 2000 Process_Date: 2009 Process_Step: Process_Description: Fieldwork - Reconnaissance field work was done in the summer of 2008 during which observations were recorded for use during aerial photograph interpretation. In July-August 2009, field work to verify aerial photograph interpretations was performed. In addition to observations from ground and helicopter 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, highway cuts, and trenches dug as part of active fault studies were recorded.
