Into Spider Hole Cave, Northbend Sink

Northbend sink cave aka. spider hole cave is a very small cave located right next to the road going down pigeon mountain on the petty johns cave side. you climb into a very warm pit and the entrance is a tight squeeze at the bottom. Once in It drops about 40 feet down through a series of drops that eventually leads to a short tight horizontal passage. we heard it connects to the stream passage in petty johns below but It would be really tight. There are big black spiders and huge groups of cave crickets everywhere in the cave.
