Miguel Carmona and I climbed this incredibly aesthetic route in 1988, after several years of trying. In fact, when we first heard about the Fin in 1983/84 it had no routes on it. We were just too slow to figure out the logistics. Ours was the third ascent of the route. This is not just recommended, this is a MUST DO route, for anyone, who loves backcountry climbing, solitute and challenge. The approach is a challenge too, but well worth it. We brought two sets of clothes, so we would minimize the Poison Oak exposure. We hiked in one set (long sleeve shirts, long pants, long socks, thin gloves,hats and scarfs) and climbed in the other set. The route is sustained and runout. Two medium and two serious ones. The topo that Craig Clarence drew is very good and the route can be followed from it just fine. I wrote a TR all those years ago on the SCMA web site and if you are looking for some tidbits of info, go to www.rockclimbing.org and Trip Reports to read it. I would be happy to mail you my notes, I have ton of stuff on this and Castle Rock Spire.
