This data release is a digital representation of the metamorphic map shown on sheet 2 of the bedrock geologic map of Lyons and others (1997). The original publication from 1997 was available in paper only. A scanned raster version of the 1997 map was obtained from the National Geologic Map Database catalog and converted to the geologic map schema known as GeMS.
