Yosemite National Park: A Natural-History Guide to Yosemite and Its Trails Book

This book includes an interesting section on the natural history of Yosemite and excellent trail descriptions from what we could tell. We hiked and camped on one less-popular trail and it was useful to have some of the descriptions and landmarks as described in the book (because we only talked with a volunteer ranger who was unfamiliar with the trail). The descriptions of the popular hikes we did were also interesting and accurate- it was awesome to know the names for some of the wildflowers we saw.
