Even if this was the only outstanding route at this little crag (and it isn't), Knife Crack alone would make a visit to Griffin's worthwhile. Finger crack climbing at its finest with plentiful protection; the only thing wrong with Knife Crack is that it's too short.
Follow the jagged crack, using finger locks and foot jams, to a ledge with anchors below the roof. The crux is down low; things ease up some with better feet further up the crack.
A short distance down the trail from the waterfall; starts about 10' right of Whetstone.
Small to medium gear (cams/tricams/nuts); ring anchors.
Placing gear higher up.
Me on Knife, Dustin belaying. Grace Under Pressur...
At the start with a lot more to go.
