I have gone through several hardcopy versions of this map as well as having it on my phone, this map is a must-have for any winter-time Wasatch backcountry traveler. Kudos to Steve Achelis for highlighting the slopes over 30 degrees, a brilliant feature for planning tours.
I have the app and the hardcopy. If you don't have the app, get it. I use it pretty much every outing. Hardcopy I keep in my car for the ride up when picking objectives for the day. While not a hard and fast rule having the map point out in red when slopes get steeper than 30 degrees is a nice guide.
I have the hardcopy and the app. Use both regularly when planning trips, am out on trips and lost, am out on trips and want to know what something is to plan for a later trip, and to be able to explain to nonskiers what I do. It doesn't work for that last one, but it looks impressive. I haven't had an emergency where I needed to call for rescue for me or others, but this is the same map with the same names used by mountain rescue/avalanche teams. 11/10 recommend
