Slowly receeding back into the Earth

When I first stumbled on this barn last year it was badly bowed in the center of the roof.  After last Winter's severe weather and heavy snowfalls the roof collapsed on the left end.  I imagine it will be fully collapsed after next Winter's snow.  I've seen this barn labeled as the "Bull Barn" on old maps of Lusscroft Farm which begins directly across the road but it was not clear if it was actually part of that farm or a barn on another independent farm.
