"All the boulders at rattle snake are granite, and range anywhere from 10x6 feet, to 15x40 feet.- and v-0 to v12. There is also a (45 foot high) wall at the top of rattle snake, with many routes and problems that have to yet be a climb. Its also a plus that after a long day at the crag ,crescent lake provides you with a way to cool off. The boulders there range from slab climbing to all arete climbs, and there are some v9 v10s that incorporate a over hang or two. ( the only thing i dislike about the boulder feild , is that there is very few unique holds, and mostly all sloper after sloper)"
