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.

Satellite imagery taken on Wednesday shows the devastating aftermath of the Fourth of July floods in Texas. The looped video below includes images of Camp Mystic near Hunt, Texas, where 27 girls and counselors were swept away early Friday morning by a flooded Guadalupe River.

More than an hour passed between Camp Mystic receiving a severe flood warning and a decision to evacuate young campers asleep in cabins by the Guadalupe River.
