Using PC-based Geographic Information System (GIS) software, the existing geologic map has been updated and simplified by adding recent fill deposits and combining units of similar genesis, composition, and age that are also recognizable in the subsurface. The GIS database consists of a USGS geologic map and over 4,000 geotechnical boreholes and water-well logs provided by numerous public and private sources. Geologic cross sections were developed by using GIS to project graphic lithologic logs into scaled vertical layouts along selected lines. Stratigraphic units were manually correlated using the log sections as guides. Identification and correlation of subsurface units are somewhat hampered by complex glacial geology, sparseness of deep boreholes, and significant variation in lithologic descriptions among many drillers. Although these limitations result in some generalized, undifferentiated geologic units, the differences among interpreted units are of the level desired by the geotechnical user community for highlighting engineering and seismic behavior. Purpose: The purpose of this project was to acquire existing surficial geologic and subsurface data, both borehole and well-log, and incorporate it into an updated and simplified geologic map and cross sections of central and east Anchorage. Supplemental_Information: The layers listed below are present as ArcGIS shape files. 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 "PIR1999-1_codeset.pdf". Layers include: >anch_boreholes_font_point borehole and well log locations >bcc_elmendorf_region approximate surface extent of Elmendorf-age outwash deposits >bcclimit_polyline approximate subsurface limit of thick, fine-grained facies of Bootlegger Cove Formation (BCF) >geology_region geologic unit polygons Time_Period_of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 1999 Currentness_Reference: publication date Status: Progress: Complete Maintenance_and_Update_Frequency: None planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -149.941055 East_Bounding_Coordinate: -149.642279 North_Bounding_Coordinate: 61.252123 South_Bounding_Coordinate: 61.067689 Data_Set_G-Polygon: Data_Set_G-Polygon_Outer_G-Ring: G-Ring_Point: G-Ring_Latitude: 61.07 G-Ring_Longitude: -149.64 G-Ring_Point: G-Ring_Latitude: 61.25 G-Ring_Longitude: -149.66 G-Ring_Point: G-Ring_Latitude: 61.25 G-Ring_Longitude: -149.88 G-Ring_Point: G-Ring_Latitude: 61.21 G-Ring_Longitude: -149.94 G-Ring_Point: G-Ring_Latitude: 61.11 G-Ring_Longitude: -149.93 G-Ring_Point: G-Ring_Latitude: 61.07 G-Ring_Longitude: -149.83 G-Ring_Point: G-Ring_Latitude: 61.07 G-Ring_Longitude: -149.64 Keywords: Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: geoscientificInformation Theme: Theme_Keyword_Thesaurus: none Theme_Keyword: Borehole Logs Theme_Keyword: Geotechnical Theme_Keyword: Ground Water Theme_Keyword: Well Logs Place: Place_Keyword_Thesaurus: None Place_Keyword: Anchorage Quadrangle Place_Keyword: Chugach Mountains Stratum: Stratum_Keyword_Thesaurus: None Stratum_Keyword: Bootlegger Cove Clay Stratum_Keyword: Bootlegger Cove Formation Temporal: Temporal_Keyword_Thesaurus: None Temporal_Keyword: Holocene Temporal_Keyword: Pleistocene Access_Constraints: This report, map, and/or dataset are available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

Data_Set_Credit: This research was partially supported by the U.S. Geological Survey (USGS), Department of the Interior, under USGS award number 1434-HQ-96-GR-02713. Additional Acknowledgments: Geology modified from Schmoll and Dobrovolny (1972). Digital cartography by R.A. Combellick and S.M. Weems, with suggestions by A.L. Schell. R.D. Reger and P.J. Haeussler provided helpful comments on the draft map and cross sections. Native_Data_Set_Environment: Microsoft Windows XP SP2, ArcGIS 9.+, and any text editor. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Geologic point, line, and polygon data were derived by digitizing the geologic map by Schmoll and Dobrovolny (1972), then combining selected units. The location of the 30-ft isopach of Bootlegger Cove clay depicted in the layer pir1999-1_bcclimit_polyline was estimated by identifying boreholes in which soft, fine-grained deposits of the Bootlegger Cove formation have a continuous or nearly continuous thickness of 30 ft (10 m) or more. Hence this isopach is interpreted and its horizontal accuracy is unknown. With the exception of digital water-well logs, for which geographic positions were provided by the supplying agency, all borehole locations in the layer pir1999-1_anch_boreholes_font_point were digitized in GIS from project site maps provided with the drilling reports. The scale and detail of these site maps are highly variable, resulting in variation in accuracy of the digitized locations. See the Horizontal_Positional_Accuracy_Report below. Logical_Consistency_Report: Polygon topology present and clean on appropriate data. Other data are line, point, or annotation data and do not require topologic relationships. Completeness_Report: This dataset includes geospatial information related to geologic map units and borehole localities. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The accuracy of geologic unit boundaries in the layers pir1999-1_geology_region and and pir1999-1_bcc_elmendorf_region depend on the accuracy of the original geologic map by Schmoll and Dobrovolny (1972) and the accuracy of digitizing. In the layer pir1999-1_anch_boreholes_font_point, the attribute "location_method" is a code indicating the method by which the borehole or well log locations were determined (see Entity_and_Attribute_Information). Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 50 Horizontal_Positional_Accuracy_Explanation: Accuracy of boundaries of mapped geologic units in meters. Considering that geologic units on the original map were primarily photointerpreted on the basis of landform boundaries, the unit boundaries should be accurate to within several tens of meters, however there is no documentation of position accuracy in the original publication. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 100 Horizontal_Positional_Accuracy_Explanation: Positional accuracy of boreholes and well logs that were located from original site or parcel maps at scales of 1:24,000 or greater is estimated to be between 10 and 50 meters. Positional error of boreholes or well logs for which the location was not known within a parcel or 3rd or 4th quarter section (location method 6 or 7) could be up to 100 meters. There are no boreholes in the database located by method 8 (center of 2nd or 40-acre quarter section). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Measurements of boreholes and wells for the attribute "FT" in the layer pir1999-1_anch_boreholes_font_point were taken from the original driller's reports, which do not contain information about measurement accuracy. Depth is generally reported as the total length of drill string below ground surface, including the auger and all drill rods. Quantitative_Vertical_Positional_Accuracy_Assessment: Vertical_Positional_Accuracy_Value: 5 Vertical_Positional_Accuracy_Explanation: The maximum vertical error in feet of the borehole depths. The driller's estimate of length of total drill string could be off by several feet. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Schmoll, H.R.

Process_Step: Process_Description: Geologic map compilation - Map data compiled for the GIS database include five 1:25,000-scale U.S. Geological Survey (USGS) topographic quadrangles and a carefully digitized version of the most recent geologic map of Anchorage (Schmoll and Dobrovolny, 1972). The topographic maps were digitally trimmed and spliced seamlessly together, then geographically registered to provide an accurate base map for the geology and for digitizing borehole locations. All geotechnical borehole data and some water-well data were obtained in paper form from public agencies and private companies that have drilled significant boreholes in the Anchorage area since the late 1950s. The U.S. Geological Survey provided most of the water-well data in digital format from its Groundwater Site Inventory System. Source_Used_Citation_Abbreviation: Schmoll and Dobrovolny, 1972 Process_Date: 1999 Process_Step: Process_Description: Revision of geologic map: The geologic map on sheet 1 is based on an existing map (Schmoll and Dobrovolny, 1972), with four features that distinguish my simplified map from their original: (1) Grouping of units to create a simpler map with fewer geologic units highlighting differences in materials content and gross physical properties that are of engineering significance and can be recognized in the subsurface in borehole and water-well logs. (2) Updating of geology using interpretation of 1993 color vertical aerial photographs, primarily by adding significant artificial-fill deposits that have been emplaced since 1972. (3) Updating of topographic base map to those revised in 1993 and 1994. (4) 30-ft isopach of Bootlegger Cove clay through inspection of ~300 borehole logs to identify those in which soft, fine-grained deposits of Bootlegger Cove Formation (BCF) have a continuous or nearly continuous thickness of 30 ft (10 m) or more.
