Andy Dixon has given the boulders a comprehensive update. Please click the link below for his updated topo:
The problems are listed on UK Climbing if you want to tick them: https://www.ukclimbing.com/logbook/crags/crummack_lane_erratics-23163/
The original page from 2016:

These combine well with a trip to Thieves Moss.
