Robert “SP” Parker 2010 - 2nd Edition 96 pages 5.5” x 8.5” No ISBN Self Published The Guide’s Guide to Sierra Waterfalls and Alpine Ice Routes. This print guide has been a long time coming. Waterfall ice climbing in the Eastern Sierra of California started in the 1960s and the alpine ice has been climbed since the 1920s. But until now there has been no comprehensive guide to these routes. Short approaches for a fun day of climbing or long multi-day excursions in the backcountry; it is all here.
