Moose's Mantle

Start by straddling the north-most arete (the right arete, if facing the boulder's east face) with one hand and one foot on each side. Move up a little and traverse left (south) until you've cleared a large shelf above you. With the shelf just up and to your right, climb straight up and mantle over the top (the climb's hardest move and namesake.)

The top of the shelf is off limits. No hands or feet on top of the shelf, though it'd likely make a more relaxed variant.

While facing the east-facing side of the boulder, this problem starts on the north-most arete (the right side.) It is the furthest north start possible on the east face.

One bouldering pad to protect the mantle. A second pad (or a spotter moving a pad) is nice to protect the start.
