It stretches from the Brooks Range on the north, to the Kuskokwim River and lower reaches of the Yukon River on the south, and from Kotzebue Sound, Seward Peninsula, and Norton Sound on the west, to the Yukon-Tanana Uplands and Tanana-Kuskokwim Lowlands on the east. The region is characterized by isolated hilly areas and low mountain ranges separated by broad alluviated interior and coastal lowlands. Most of the lowlands, except those bordering Kotzebue Sound and Norton Sound, support a heavy vegetation cover. Exposures of bedrock are generally limited to rubble-strewn ridgetops and cutbanks along rivers. The data was compiled largely from geologic field data collected between 1953 and 1986 by the U.S. Geological Survey and published as 1:250,000 scale geologic quadrangle maps. Additional data for parts of the Wiseman, Ruby, Medfra, and Ophir quadrangles came from 1:63,360 scale quadrangle map published by the Alaska Division of Geological and Geophysical Surveys. This compilation also incorporates unpublished field data. This data set is also a portion of a statewide geology database, which is being compiled by the U.S. Geological Survey's National Surveys and Analysis (NSA) project, whose goal is to compile geologic, geochemical, geophysical, and other data. Purpose: This data set represents part of a systematic effort to release geologic map data for the United States in a uniform manner. Geologic data in this series has been compiled from a wide variety of sources, published and unpublished, ranging from state and regional geologic maps to large-scale field mapping.

Wilson (USGS) and Solmaz Mohadjer (contractor) Native_Data_Set_Environment: Data set was created using ESRI ARC/Info version 7 on a Unix platform Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The original source materials for this data set are from various scales (1:63,360 to 1:250,000), medium (digital, mylar, paper), and scope (bedrock, surficial, tectonic). All vector features were originally hand digitized on a large digitizing tablet or on screen. Vector and polygon attributes were assigned based on the original source. The digital data has been visually checked, and the geologic map has been technically reviewed and edited. Logical_Consistency_Report: Each geology coverage is a network coverage containing attributed arcs and polygons. Each polygon has coded a attribute designating the mapped geologic unit. Faults, stratigraphic contacts, and other linear features are represented as arcs. When a fault is also a stratigraphic contact, only a single arc is present. Dangling arcs may be present (faults, dike, etc.) Completeness_Report: The complete data set consists of the GIS files and an associated database of geologic units. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: This data is presented for use at a nominal scale of 1:500,000, although individual datasets may contain data for use at larger scales. Details within the attribute tables and metadata provide information on map sources and the appropriate scales for use. Lineage: Process_Step: Process_Description: Linework for the geology compilation was hand digitized from material of various media and scale. The arcs and polygons were attributed. The spatial databases are provided in UTM projection and geographic coordinates. The native ARC/Info coverages have been exported to an interchange file format, .e00, and also converted to Arc/View shape files.

The table .pat includes the following items: CLASS, NSACLASS, NSAMOD, QCLASS, SOURCE, LABEL, MIN_AGE, and MAX_AGE Entity_Type_Definition_Source: This data set Attribute: Attribute_Label: NSACLASS Attribute_Definition: NSACLASS is a positive integer value (4 5 B) item in the polygon attribute table. Values range discontinuously from 100 to 9325. NSACLASS is a numeric code for the geologic unit. This data set represents a generalized map, thus it is possible that a geologic unit is made of multiple NSACLASS values. Some map areas include more detailed Quaternary mapping, requiring some of the NSACLASS values to be subdivided. These geologic units are attributed in the .pat item QCLASS. Each NSACLASS or QCLASS matches with geologic unit labels in LABEL and has a minimum (MIN_AGE) and maximum (MAX_AGE) range, given in million of years (my). Supplemental attribute tables included with this data set, contain additional descriptive information of each geologic unit. A user may use items SOURCE and CLASS to retrieve information about the original units from which these generalized units were formed. NOTE: Because of the limitations of common GIS fonts, the letters "Mz", "Pz", "Tr", and "Pa" are substituted for the standard symbols for "Mesozoic", "Paleozoic", "Triassic", and "Pennsylvanian."
