Mobile-Friendly Maps

The Avenza free mobile app makes it easy to download forest maps onto your mobile device. View a list of available maps in the Pacific Northwest by area below or visit the Forest Service, Rocky Mountain Region Avenza library to search for all available maps in the region.

Avenza maps are georeferenced so that you can find your location on the downloaded map, even without WiFi or network connectivity. The GPS on your mobile device can use your location to pinpoint you on the map with a blue dot, and the dot follows you as you go. Learn more about georeferenced maps

Safety Reminder: Never count on your cell phone map as the only navigation device out on the trail, especially in the backcountry.
