Treehouse is fun, flowy, and has a great view into Bear Canyon. Begin at the far left of the boulder (before it drops down towards Hanging Garden), and start sitting down with a left hand edge in a little corner and your right hand on another down-pulling edge. I do two hand movements before reaching a left handed jug. From here, you reach out right to a vertical crack, match it, and then go up to jugs.

It's about 10-12 feet to the lip, but I think it's fun to climb the slab all the way to the top of the boulder...just be careful. To get down, I hop off near the jugs at the lip.

If I am wrong about getting the first ascent, please reach out, and I'll update.


If you are looking at Dinosaur Rock from the Mallory Cave trail, continue upwards along the trail till you're near the top of the formation. Head towards the top of Dino Rock, and you should see a very large boulder to the right of it. Follow along the left side of the boulder (you are walking between Dinosaur Rock and this large boulder) and at the end of it, before a drop off, you'll see Treehouse.
