I'm cramming for an upcoming trip to the Sierra Nevada range,up, over, and around, so am about a third through The Sierra Nevada, Naturalist's Guide, which sends me spinning off to other references, such as the charmingly lyrical A Natural History of Western Trees, by Donald Culross Peattie, The Complete Trees of North America, and such page-turners as Geology Underfoot in Death Valley and Owens Valley.
