There is a cave NE of Huntsville, "Dry Creek", that is only accessible during severe droughts, like the one now. It is in serious need of a re-survey. The existing survey was done by a French Canadian team 25 years ago, using Topofil. The original explorer believes there is an error in the existing survey, but he can't dive anymore, and wants to see a re-survey done.
Anyone interested in helping with a re-survey, contact me at sumpdiver@cavediver.net
