Shapefiles of the map data that were exported from the file or personal geodatabase.
Either a style file or, for HSDM maps created in ArcView 3x, a legend (.avl) file specific to each map to aid in symbolizing.
FGDC_GSC style file for bedrock maps created after 2013 in the NCGMP09 standard format, where FGDC codes were used for symbolizing.
Excel file with explanation of abbreviations for surficial maps.
Metadata specific to each file:
The field used to symbolize each shapefile is noted under Resource Details.
A Code Key for surficial map codes is given in the Description.
The exceptions to 2 and 3 above are some earlier HSDM surficial maps that do not have a file to symbolize on. All surficial maps do however have an explanation of abbreviations included in the zip file and a Code Key in the metadata Description for explanation of surficial units.
Note: The shapefile package does not contain annotation layers due to limitations of the software.
