Motor Vehicle Use Map

The motor vehicle use map (MVUM) is the official map of open designated roads and trails available to motorized travel in the Bighorn National Forest. The Bighorn Motor Vehicle Use Map can be downloaded on to a tablet or phone through the free app by Avenza Systems, Inc. You can use the maps based on your location when GPS is enabled and available. The maps allow you to measure distance and area, find coordinates, open a current view in Google maps, plot place marks, add notes, enter your own data, and add photos as attributes.
