Short but immaculate and almost perfectly-vertical block in the upper section of Snowshed east. The wall faces north and is generally shaded all day. Though seemingly blank from a distance, the wall is littered with a variety of small edges, and contains the classic crimpfest Brain Child, as well as a hard, bouldery line to its left that sees few repeats. There are a number of linkups between these two routes, as well as a quality addition to the Snowshed arête series called Missing Mind.

Approach as for Snowshed East. The brain block is the north facing wall just above the main east face.
