  • Description 

    One of Tuck's defining features is a large, left-facing dihedral that arcs up steeply into a roof. In this dihedral is a very small crack that runs the length of the vertical dihedral. Follow this corner in, up, and finally out through the top.


    Very tiny stuff for lead, slings for TR.

    Fun! Well named -- Tony Bubb calls it a study in the angles of forces.

    Good climb. We wondered why, in Rossiter's Boulder Canyon guide, Hypotenuse was starred but Boiling Point, the more obvious and nice looking cracks to the right was not starred. Hypotenuse has interesting stemming moves. There are sloped ledges and holds on the left wall, but the right wall is essentially blank much of the way. Gear ranges from brass nuts and microcams to #1 and #2 Camalots.

    I see I am wrong about Boiling Point being the cracks right of Hypotenuse. Boiling Point seems to be further right around the corner, facing the road. What are the cracks just right of Hypotenuse?

    Three routes in this little rock.
    Stay left into the dihedral, lots of fun. I would say 5.9.
    Run the finger crack up the center, only two moves make this a climb otherwise its pretty simple. 5.8+ maybe a 5.9.
    Then run the nose to the left, very simple a little chossy. I would say 5.6 or 5.7.

    Super classic. Fun easy stemming moves around a roof. Good rock and steep without difficulty make this a classic.

    Bring your baby Aliens/small stuff, this climb can be thin! The bottom of the dihedral currently sports a fixed WC Zero. I placed an okay nut above that and then a black Alien protecting the crux. Once through the crux, a great #1 C4 can be had. Enjoy!

    I'm not sure which guidebook you guys are using, but for the last 34 years, Hypotenuse has always been the thin crack in the face to the right of the corner. To quote Erickson's book 'Rocky Heights' from 1980: "a prominent, open book on the right hand rock. Climb a thin crack on the right hand wall (5.9+)."

    Climbed both the corner (lead) and the thin crack on the face (TR). Both could be considered dicey for gear by modern standards. Both lines are super fun.
