Has anyone suggested OnX Maps to find BLM and other area info? They’re a startup out of my hometown of Missoula, MT, and most of us here at GFC swear by the app. It’s constantly updated, and their recent entry into the backcountry skiing space shows that they can iterate to success quickly.
The off-road app is likely what you’ll want to look into, and the overall features are solid from planning to recapping your trips. Plus, it’s 30% off until 2/25.
