There were chalked holds on the 1st boulder with the overhanging face(non chipped) looks like it could be decent hard problem. At least v8 or harder.
When I was out there a couple years ago there had been no recent sign of climbers, although I do recall and old pin or perhaps just a drilled hole on top of one of the boulders for some top roping....
Will have to check this out, live in Shirley, MA. if anyone want to check these out one day that its not 5 degrees out. Jeff
I live in Littleton I've been wanting to check them out too but as you mentioned it's horrendously cold.. Hopefully soon
