This is a really cool app that allows you to explore USGS topographical maps. Pinch-n-zoom, place waypoints, and export to your computer – this is an excellent tool that will get a lot of work as I prepare for our June Long Trail hike.
Cost is $7.99 for the app, but you can download as many topos as you want for free. Only downside is that many trails don’t appear on the map – (although the Long Trail does.)
Here’s a link to the iPad version:
