About This Trail

Imported description

The trail leads down a hill to a opening in the Earth. The trail goes down the canyon to the caves and caverns that are abundant in limestone. It is a little difficult in the bottom but can be done back up the hill. You will see Limestone ledges with little to no cache. You wonder why the people of the past liked it so much. The wonders are plentiful.
