Description
This 30×60 minute map, provided as a digital GIS dataset, is a 2022 compilation of the original 1989 USGS map Surficial geologic map of the Meeker 30′ X 60′ quadrangle, Garfield, Moffat, Rio Blanco, and Routt Counties, Colorado. This particular compilation includes a surficial geodatabase set. It was funded as part of a supplemental USGS STATEMAP program grant. Further details on the compilation process and provenance are available in the various metadata forms found in the package. The 30×60 minute map is a download package of GIS data only: no map plate or report. Digital ZIP download. OF-22-15D
From the map metadata:
The purpose of this dataset is to describe the surficial geologic setting of this 30×60 minute sheet. The original geologic map, USGS I-1823, was published in 1989 and included surficial units. The map was scanned and georeferenced. Digital Data Services digitized the map units, contacts, faults, geologic lines (including dikes and unconformities), and relative fault movement (shown as D on the down thrown side of the faults in the generic points feature class). The data was then imported into a GeMS style geodatabase. Topology was applied using the GeMS topology rules and then the gdb was validated using the GeMS validation script. The map was validated to Level 3.
