In prep for going to Lumpy Ridge this week, we decided to go back into Boulder Canyon; climb on some granite, and work on some finger-jam cracks to push my grade. (Lumpy is notoriously stiff.)
Cob Rock was the obvious choice being so assessible.
This is another roadside park, Tyrolean over Boulder Creek, and up a short scramble. We started up a 5.6+ which was a real struggle for me; but I did it. Then we moved onto the main 5.7+ route up the center of the north face. Parts were straightforward, but one off-width crack, and a second jam crack really gave me trouble. Took my first real fall off the wall at one point, and even had to jug up the line to get around one section. (Involves tying special knots with slings and standing up on the sling to move up the rope. Total cheat, but when your completely stuck on a face, up is up!) Fortunately we had just been practicing this the previous day.
When we left, we discovered some local kids had rigged a slack line under the Tyrolean making for some unexpected fun on the exit!
