Digital Geologic-GIS Map of Lake Clark National Park and Preserve and Vicinity, Alaska (NPS, GRD, GRI, LACL, LACL digital map) adapted from a U.S. Geological Survey Scientific Investigations Map by Wilson et. al. (2015), and U.S. Geological Survey Open-File Report maps by Bickerstaff, Hawley, Huber, Hudson, Millholland, Riehle and the U.S. Geological Survey (1998 to 2008)

Metadata Updated: December 11, 2019

The Unpublished Digital Geologic-GIS Map of Lake Clark National Park and Preserve and Vicinity, Alaska is composed of GIS data layers and GIS tables in a 10.1 file geodatabase (lacl_geology.gdb), a 10.1 ArcMap (.mxd) map document (lacl_geology.mxd), individual 10.1 layer (.lyr) files for each GIS data layer, an ancillary map information document (lacl_geology.pdf) which contains source map unit descriptions, as well as other source map text, figures and tables, metadata in FGDC text (.txt) and FAQ (.pdf) formats, and a GIS readme file (lacl_geology_gis_readme.pdf). Please read the lacl_geology_gis_readme.pdf for information pertaining to the proper extraction of the file geodatabase and other map files. To request GIS data in ESRI 10.1 shapefile format contact Stephanie O'Meara (; see contact information below). The data is also available as a 2.2 KMZ/KML file for use in Google Earth, however, this format version of the map is limited in data layers presented and in access to GRI ancillary table information. Google Earth software is available for free at: Users are encouraged to only use the Google Earth data for basic visualization, and to use the GIS data for any type of data analysis or investigation. The data were completed as a component of the Geologic Resources Inventory (GRI) program, a National Park Service (NPS) Inventory and Monitoring (I&M) Division funded program that is administered by the NPS Geologic Resources Division (GRD). Source geologic maps and data used to complete this GRI digital dataset were provided by the following: U.S. Geological Survey. Detailed information concerning the sources used and their contribution the GRI product are listed in the Source Citation section(s) of this metadata record (lacl_geology_metadata.txt or lacl_geology_metadata_faq.pdf). Users of this data are cautioned about the locational accuracy of features within this dataset. Based on the source map scale of 1:1584,000 and United States National Map Accuracy Standards features are within (horizontally) 804.7 meters or 2640 feet of their actual location as presented by this dataset. Users of this data should thus not assume the location of features is exactly where they are portrayed in Google Earth, ArcGIS or other software used to display this dataset. All GIS and ancillary tables were produced as per the NPS GRI Geology-GIS Geodatabase Data Model v. 2.3. (available at: The GIS data projection is NAD83, Alaska Albers, however, for the KML/KMZ format the data is projected upon export to WGS84 Geographic, the native coordinate system used by Google Earth. The data is within the area of interest of Lake Clark National Park and Preserve.
