U.S. Forest Service offers new digital maps for mobile devices

"The digital maps are part of USDA’s work toward reaching President Obama’s initiative to create a paperless government that also provides the American public with better, more accessible information." They are available for Andriod and iOS devices.

You can use the app online in areas with wireless access, or download the pdfs to your device. Basic maps like road maps are free, and other maps can be purchased through the app as needed.
