This is The Mental Block.
Dave Kellermann on the first ascent of Hippo Campus, V4, on the incredible Mental Block, a boulder that is about ten times the size of The Citadel (with Ammagamma of course). In 2011, Mike and Dave Kellermann, Sophie Vivian and Mike Forward developed about 140 boulder problems in the sector. We did almost every line on The Mental Block (about 15), including a problem that is one of the best few lines in the country: Mind Over Matter, V8 (see upcoming video). Spotter: Mike Kellermann.
