FATMAP is Shutting Down. Meet onX Backcountry, Your New Map App

The outdoor community is constantly evolving, and the tools we use for planning and navigation must do the same. As FATMAP has shut down their app and web map, we understand that many of you are faced with the tough decision of replacing a trusted resource. As avid skiers, backpackers, hikers, climbers, and mountain bikers, we at onX Backcountry have built the best planning and navigation tool for human powered adventurers in the US. We are confident that switching to onX Backcountry will provide a seamless transition to your new trusted mapping tool. 

Your All in One GPS Mapping App

The onX Backcountry App is the ultimate tool for your next adventure. No matter how you’re exploring the outdoors — whether it’s skiing down a snowy mountain, escaping to the desert for mountain biking, searching for climbing routes, or planning a backpacking trip — use onX Backcountry to find routes, navigate terrain, save maps, find public land, and access thousands of recreation points all year long.

Detailed 3D Maps

Understanding the landscape is crucial in avalanche territory, and onX Backcountry’s 3D Maps are an essential tool for planning your routes with precision. When you can visualize slope angles, elevation changes, and potential avalanche paths, you can identify safe routes and avoid hazardous areas. 

Curated Guidebook Content

With more than 3,300 professional guidebook ski routes across 35 mountain regions, onX Backcountry gives you the information you need to get out and explore. These guidebooks are written by local expert guides and authors who know the terrain and offer detailed route descriptions, essential safety information, and expert tips. Whether you’re exploring new terrain or finding new lines on your home turf, we have you covered. 

Slope Angle

The Slope Angle layer in mapping tools displays the steepness of terrain, helping users assess how steep a slope is. It’s especially useful for backcountry skiers and mountaineers to evaluate avalanche risks and route difficulty.

Avalanche Layers

Identifying avalanche-prone areas and making informed decisions is critical, and the Backcountry App’s Avalanche Safety Layers put the information in your hands. From the Avalanche Terrain Exposure Scale (ATES) Layer which categorizes terrain based on risk, to the Avalanche Potential Release Area (PRA) Layer which pinpoints zones with a high likelihood of release. Combine the two to stay safe and explore with confidence. 

Know Where You Stand

Seeing public and private land boundaries is easy with onX Backcountry. Ensure you’re on the right side of the line at all times, particularly when exploring new areas. Whether you’re planning a tour in a National Forest, on BLM land, in Wilderness Areas, or anywhere else, the onX Backcountry App allows you to know exactly where you stand. 

Offline Maps

Before you head out, quickly download your maps to your phone so you always have access—even when cell service is miles behind. All of your Markups and critical map information are retained in Offline Mode, providing peace of mind and reliable navigation in the backcountry. 

Our Commitment to Community

Designed for and by backcountry adventures, onX Backcountry works closely with avalanche forecasters, educators, mountain guides, and guidebook authors to help you plan safer tours. These partnerships allow us to build the features for users of all skill levels, and incorporating guidebook content provides expertly curated routes and safety tips to enhance your planning and decision making. onX Backcountry is much more than just a navigation tool. It’s a comprehensive resource that supports safe and informed exploration in avalanche-prone terrain.
