Veteran author and backcountry explorer Erik Molvar discovered backpacking while working on a volunteer trails crew in the North Cascades of Washington. He is the author of more than a dozen FalconGuides for such places as Glacier National Park, the Bob Marshall Wilderness, Olympic National Park, Zion and Bryce Canyon National Park, as well as Hiking Colorado's Maroon Bells-Snowmass Wilderness.
I used this book to help plan a backpacking vacation in Glacier National Park during summer 1998. I was very satisfied with the information and descriptions provided by Mr. Molvar. As I knew little about the park beforehand, planning this trip would have been nearly impossible without this book. Contains text, simple maps, elevation gain/loss charts, backcountry campground info and ratings, advice, warnings, etc. I can not say enough good things about this guidebook!
We used this when planning a backpacking trip at Glacier in 2011 (we went in and out through Ptarmigan Pass). We thought it was a useful book, well written, with a good level of detail that helped us choose an appropriate route. We trusted it enough that we later bought Molvar's book for our next backpacking trip to Olympic National Park.
