Jacob's Well is a spring fed well just north of Wimberley, TX. Cave divers with the Jacob’s Well Exploration Project have mapped over 6,000 feet of underwater passage with a maximum depth of 140 feet. It contains one of the longest underwater caves in Texas and nine divers has lost their lives exploring the cave over the years. These two boys are brothers that were daring each other to jump first as I took the shot.

Be sure to check online for open hours, possible fees and the need for reservations.
Wow! That brave I may never be! I am betting it is a neat feeling though. By the smile on your face, you were enjoying every minute of your leap!
Sometimes it's good to take a leap of faith!
Thanks for your comment,

Looks like they are jumping into the abyss. Must be a neat place to visit. Those youngsters are more brave than I am. 🙂
