Over Snow Vehicle Use Maps (OSVUMs)

The OSVUM is a color map with no topographic features. It is a map for legal designations of where you can travel with over snow vehicles, but for additional reference it is best used in conjunction with a Forest Visitor Map or other detailed map.

There is one Over Snow Vehicle Use Map (OSVUM) that covers the western portion of the Custer Gallatin National Forest.  This map has a front cover and 9 detail maps on the back.

Hardcopy OSVUMs are available at the Hebgen Lake, Bozeman, Yellowstone, Gardiner, and Beartooth Ranger District Offices.

Digital MVUMs are available for download at the links above for use on mobile devices, or from the Avenza store.

Both digital and hardcopy OSVUMs are provided free of charge.
