[Hide Comment] The last few moves are scary. Slopers and trying to top out, good luck. Aug 17, 2016

[Hide Comment] I think this is one of the better climbs in the park, much to my surprise. The movement is fun and flowy, the top is committing and the boulder is tall enough to stand out amongst the crowd.... literally! May 18, 2022

[Hide Comment] Definitely not a clean top out but I’ll be back for a cleaner send soon! Really sick line!

[Hide Comment] Lower part of climb is great, top-out is a bear. A fall off the top would be less than ideal. Beta: youtu.be/NIY0V_U9omU Aug 18, 2025
