I don't often bring this up because it was a long time ago, and when I think of it I literally shiver. Cooper Branch is a small tributary of Bisphams Creek in Lebanon State Forest. It eventually runs into the Rancoacas. My first true exploration in 1976 was to walk down the center of Cooper Branch by starting out by the Lebanon Glassworks, and following it down to Pakim Pond. We were halfway down when I heard the shrieking cry of a woman. It was very loud and clear, and definitely not an owl. It sounded like a mixture of anguish and anger. I was very uncomfortable as it was dusk and the cedars were closed in tight against me. I had on hip boots and could not really move fast.
I never went back, and to this day I cannot explain it.
