This boulder has a low, "dugout" roof with some cool problems on it.
In addition to the listed problems, to the right of the cave are these two climbs (that may need some scrubbing).
Dig It (V4) - SDS low, and go out a roof.
Dig In (V2) - SDS low, and climb past crimps.
From the Painted Wall, follow the faint trail left past the Swirley Wall. Stay on the same contour, and you will walk right up to this roof.
