Several ascent options are now possible on this WI2 gully that has been farmed into the addition of WI4 and WI5 routes. Someone has done a great job of making a lot out of a little here.
From the north side of Lake San Cristobal, take a left on the CR33 spur and drive along the EAST side of the lake. It will dead end at a picnic, camp, cul-de-sac area (good place to cop a squat). Walk back north up the road about 150 yards, and bust a right up through the aspens. Just head into the obvious drainage, keep to its right. The top of all the routes have heavy slings to rap or TR from.
Pure ice so far, with many more options to expand on. Or, TR from existing ropes & slings. Check all rap stations first - not all of them are new, nor should be trusted.
