Blue Spring Cave

In that year a group of cavers enlarged a hole with air movement at the rear of the cave that dropped into a large passage which they named Johnson Avenue, in honor of the owner of the property on which the cave's entrance is located.

This new entrance makes it possible to enter directly into Johnson Avenue and bypass the tight crawlway that connects the historical front 500 feet of the cave to the new discoveries.

This new length was announced by Bill Walter at the 2012 SERA Winter Business Meeting.

The footprints in Blue Spring Cave were first noticed by Bill Walter in 1990, but he did not realize how old they were.

Additional jaguar footprints were discovered by Hal Love on November 15, 2003, and, based on this discovery, their age and significance were recognized.
