The OwlsheadGPS Project covers 101 million acres of public and private land throughout the whole of the State of California. The Project features 37,116 OHV routes totaling 57,077 miles of roads and trails.
The OwlsheadGPS Project includes only routes that are within this Project Area. The route data is the same across the MapViewer, the GPS Maps, and the downloadable route files.
As funding becomes available we will expand the Project Area by obtaining and processing more official agency OHV route data. Please click here to learn how you can support the OwlsheadGPS Project.
