The Krusty Crab - 6C
Opposite the When the Days are Dead et al boulder. Sit start (bit reachy so might need to stack pads).
The other two are on a wall at the very top of the scree hill (above Spray, the 7C Tom Newberry put up).
This wall has a single bolt in it on the far left. (??)
Best accessed from above - walk onto Walls Hill as if going to Anstey's proper, but take the right-most path (heading south-ish around the cliff-top).
After the concrete ramp bit there's a way down by jumping the fence at a break in the vegetation.
I tested the choss at the top pretty thoroughly on a rope and everything I ended up using seemed solid, but probably best to test it yourself!
Deep Learning 7A
Straight up, big moves between good holds, then go right for the top-out.
Deep Learning RH 6C+
Same start but go immediately rightwards. Same finish.
