Spent this week just gone doing some work in Coldstone Quarry that belongs to Howdens. In the quarry there are several cavelets and cave entrances. Talking to Shirley (Quarry Manager) and Bob Orange (Site Manager) they informed me that the caves are known and are generally short in length being largely filed with glacial debris. On one of the old quarry faces (2nd tier) there is an entrance to a cave that has been surveyed. Out of couriosity I was wondering if anyone has any information about the Coldstone Quarry caves as info in Northern Caves seems quite sparse.
