I live in East Tennessee. By definition, I am probably living over a cave.
Old timers who used to live in the neighborhood tell of a legendary cave that “we used to throw garbage into,” “dad pushed a car into it,” and “we dropped a fishing line with a weight on it and never found the bottom” yet I have never found this entrance.
The creek behind my house on rainy days flows normally. On most days the creek has a trickle that goes underground about halfway behind the neighbor’s house. This is the strongest evidence to support a cave system.
Question: 1) How do I confirm there is a cave? and 2) if I wanted to dig an entrance to the cave, how do I know how/where to dig such that I don’t just dig right beside the cave thus never finding it?
Bonus question: If I verify my house is above a cave system, do I destroy the resale value of my home?
