Use of Global Positioning Systems (GPS) and Geographic Information Systems (GIS) For Geological Applications in the Bighorn Basin, Wyoming

Gretchen Hurley, Jodee Cole

Abstract

Global Positioning Systems (GPS) technology has been in use globally for the last decade. This emerging technology, though still expensive to acquire, is being paired with widely-used Geographical Information Systems (GIS) technology to generate extremely accurate maps and high quality graphics. These combined technologies are useful for numerous research and management functions, and are being used in the Bighorn Basin for geological and paleontological applications by the Worland District Office-BLM (WDO-BLM).

Since 1993, the WDO-BLM has employed GPS/GIS technology to delineate numerous boundaries and locations for timber sales, prescribed burns, wildlife migrations, law enforcement, recreation, archaeology and range management projects. Geological applications include location and mapping of mining claim corners and perimeters; sand/gravel pits, stockpiles and reclaimed areas; surface hydrology; bentonite and gypsum mine area boundaries; oil/gas well and access road locations; and areas of unstable soil and downslope movements. Cretaceous-age (Meeteetse Fm) fossil plant locations at the Big Cedar Ridge site have also been mapped using these technologies.

The Bighorn Basin project planned for 1996 through 1999 involves using GPS/GIS technology to accurately map known in-situ locations of vertebrate fossil remains, primarily dinosaur. Areas of questionable land ownership where fossils are located can be better resolved without costly, time-consuming land surveys. Geological and paleontological resource managers will have at their disposal a comprehensive and accurate library of maps which can be used to monitor and protect valuable resources.
