Tough, dangerous climb, but a classic if you have the skills and athletic ability.
Be aware though that Township 3 South, Range 3 East, Section 33, San Bernardino Baseline and Meridian, is private property. It's owned by the local water company, the DWA, and they are SERIOUS about no trespassing. It's one square mile of land and it sits smack dab in the mouth of the canyon that Snow Creek descends. If you want to climb Snow Creek, it's legal, so long as you figure out a way around the private property. Oh, and don't pollute the water back there. The DWA
will prosecute as several people have learned -- the hard way.

Good luck,
