Just noticed your address Catskill. I used to live in Palenville at the foot of North MT. Had a stream in the back yard with small falls and a walking bridge. Man, I miss living up your way.

Top of North MT. Behind the falls, is a large cave.
There are carvings in the rocks dated from the 1700s. (outside the cave) There are none from 1940 to 1944. (Just thought that was odd) One is (yr,18 something) in memoriam of a dog who passed due to chasing some thing right over the edge. Really touching how these 2 guys loved this dog.
