Description
This problem is on the south east side of the boulder, starting in a shallow v-shaped crevice. From the 1999 James March Rock & Ice guide, "Sit start. Roof has many variations," this is one of them. With a squished down single pad layer you can start this from a funky/awkward full sit start with the right technique. I think most people start one move above that though.
