Tsunami Sit (Tsunami Boulder)

And the sit goes! 

Start low in the cave using the block horn under the roof for your left and your right on the incut spot on the rail.  The next moves are powerful slaps out to the lip using heels and toes to get to the start of Tsunami stand.  Climb to the top.

Located in the closely clumped tier 3, the tsunami boulder is perched up the hill on a prominent talus field.

6 pad minimum. More are ideal. There are many different ways you can fall off of this thing, and some of them would lead to serious injury.  You want a spotter.
