Catastrophic flooding killed 68 people in Kerr County, Texas, alone, where water washed through an all-girls summer camp, killing over two dozen people and sparking a desperate search for missing campers.

Camp Mystic said on Monday that 27 campers and counselors died in catastrophic flooding on the Guadalupe River in central Texas.

Surviving campers sang hymns as they drove past the damage left by the floods. Days earlier, they were having fun and playing games at the all-girls’ Christian summer camp.
