Visible from the main path through the woods at Yearby, although the tree cover made GPS reception tricky.
There appears to be a second chamber through the doorway at the rear, although i had neither a powerful torch or a ladder to venture any further to photograph it.
Some sort of ladder is needed if you want to get inside (or more importantly get back out afterwards)
There is a record of a hermit called Mick Plummer actually living here.
Yearby Icehouse

One to go and visit, probably minus a ladder at this stage though! The story of Mick Plummer was worth reading, an interesting charater, he’ll certainly be in my thoughts when I make it there. Hope he doesn’t haunt the place
My sad recollection is that he had family (mother?) in nearby Yearby but for some reason (landowner?) he ended up living in a makeshift shelter under a hedge in a field entrance on the left of Yearby Bank in appalling weather. Shortly after that I heard he had died. Tragic.
