Welcome to the Indiana Speleological Survey

Simply put, our main purpose is to continue exploration and mapping of Binkley and other related caves south of Corydon, Indiana. We strive to include any cavers interested and able to help us; this is not a secret project, but does require careful coordination and organization in order to run smoothly.

Greetings, cavers!

Five cavers went in the Miller Cave entrance and proceeded back to the McLain River last Saturday, 4 October 2014. They surveyed more than 1600 feet of new passage, although there was some disappointment in discovering a sump in the downstream end of the river. I have not yet compiled a trip report of their efforts; please stay tuned.
