A ninefold compilation of the many aspects of the Sierra Nevada mountains and valleys, which includes an introduction by Donald Culross Peattie. Brower writes of winter sports, Harwell of the birds, Heald of mountain geography, Idwal Jones of history, mines, lodes and claims, Kehrlein of mountaineering, Matthes of geology, Rowntree of the wild flowers, Russell of the climate, and Tressider of the trees. There is a zeat to their writings, and a high pitch of enthusiasm for their subjects. From the rounded whole, a many faceted panorama of these mountains develops. Excellent addition to American Mountain Serves.
