Glacier Point Apron, Coonyard Pinnacle Route. From the top of Monday Morning Slab, the Glacier Point Apron rises up at only a 65° angle, but it is very smooth and crackless. After several attempts Layton Kor, Richard Calderwood, Bill Amborn, Jeff Foote and I managed to push the route to the “oasis,” a spring of good water coming out of the cliff at the top of the apron. The climbing is essentially free except for a huge pendulum. This climb rates with the hardest free climbs in the country in length, extreme difficulty and lack of protection.
