The stunning flood that killed more than two dozen campers and counselors along a river at Camp Mystic in the Texas Hill Country was the result of extraordinary rain and walls of water. Nonetheless, experts agree that information about how a camp plans for emergencies is just as important as the lunch menu and the times to go swimming.

On Tuesday, a sign that reads “Jesus Wept” was propped up on debris by the riverbank next to the camp.

Texas inspectors approved Camp Mystic’s emergency plan just two days before devastating floods killed over 27 people, mostly children, at the Texas summer camp.
