Triangulation

(This is line "B" in blue on the map of the Buttercup boulder)

Sit start on the best lip underneith with feet on the slopy ledge at the bottom. Work your way up to the left facing side pull flake.

Toss out left to a three finger pocket, and then make a deadpoint move to the "triangle" shape.

slap to the top for the sloper and find the two small crimps that are together to top out.
