Mt. Whitney guide Accurate, helped out between mirror lake and outpost, all rock. Thanks, successful summit!
Nice to have Make sure your phone does not need a network connection for your GPS to work. This worked well for me and was nice to have. Put your phone on airplane mode before your hike. Also use MyTracks.
Nice! This was really useful on my recent trip. It crashes occasionally on my evo 3d, which is a minor annoyance. A scale bar on the main map would be a helpful addition. I'm glad I bought this, thanks.
