Catastrophic flooding in Texas has devastated faith-based summer camps, including Camp Mystic, where at least 27 people have died.

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.
