The Fin is another elongate formation near the top of the hill and is host to half a dozen good routes. The crag really has some mixed lines that take a piece or two of trad gear, and a set of Camalots will suffice for everything. Overall, the climbing on The Fin is great (***), however, some of the stone can be friable so don't yard like Hell on everything. The area classic, Edge of Time (5.9) should just get its bolts upgraded with one or two new ones to turn it into a more satisfying lead. Since it is not difficult, just stay in tune and use the feet. A 60 meter rope will descend from everything, or you can walk off to the right.

Getting There 

Hike to the right around Lily Lake. Just before the bench head up hill via a climbers trail that doesn't look like much immediately. The trail takes you up along a corridor between the main climbing formations. The Fin is on the right and near the upper end of the corridor and just opposite the Dinosaur's Foot.

From pre-2009: Andrology is an ultra-classic line on a gorgeous piece of rock. In its previous state, a top rope rehearsal was highly advised for the 30 foot runout to the first clip, since the first bolt had been chopped. This start was "ankles for sure" if you blew it getting to the first clip.Andrology follows a series of huecos and exciting face climbing up the longest and steepest part of The Fin, and it puts everything else to shame in terms of high quality face climbing.

Checked this area out about a month ago cause I didn't get a chance to climb last summer and the Fin is LOADED with great steep, crimpy, clean routes. I saw about 4 more lines than posted in Gillett's guide. I was doing edge of time 2 summers ago and I overheard someone putting up a 5.13 right in the center of the Fin. Could be wrong.

My father and I have added CHAINS to the climbs Dynamometer and Andrology so that you can lower to the ground/pull your rope/TR, etc without the hastle of walking off.

A little extra help on how to find this crag - keep going on the trail right next to the lake shore. When you see a bench with a trail off to the right just before it, start heading up. That trail immediately splits, and you'll want to take the smaller more gravelly trail off to the right. Keep heading up that as it crosses the ridge trail. You can also take the ridge trail up, but the turnoff for the crag trail is a lot harder to spot that way unless you've been there before.

When in doubt, you can actually google maps to 'Edge of Time Rock'.
