North Quarry Talus 

The cube has another route to the right of the corner route. As for "The Chamber" that was the first bouldering boulder problem I did at BM it would have taken place in either 08/09 with Justin E. We had a name for it and would warm up on the formation before hitting the cube. There are also 2 other known problems in the area that are really really solid.

So far by my count there are 16 boulder problems in the North Quarry Talus, all of which are in this section except for "fourth dimension" which you (Mike) already put up in the larger North quarry section (can admins move this stuff around?). There are also by my count at least six more problems which are probably harder than v4-5 and I don't know if they have been done. I am sure some of these are the problems you are referring to.

None the less it's all good documentation.
