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.

Satellite images show the damage left behind after floodwaters rushed through Camp Mystic, Camp La Junta and other summer camps on July 4.

Before and after satellite images reveal the catastrophic impact the Texas flood had on parts of Kerr County closest to the Guadalupe River.

People awoke from water rushing around them during the early morning hours of July 4, all along the Guadalupe River in the Texas Hill Country. Residents were seemingly caught off guard, but warnings had been issued days and hours before floodwaters began carrying away homes,

Richard "Dick" Eastland, the late owner of Camp Mystic who died in last week's flooding, was aware of the dangers of the Guadalupe River and previously advocated for change in warning systems.

The bodies of 10 of the girls, ages 8 and 9, have been recovered, along with counselor Chloe Childress, 18. Three girls and counselor Katherine Ferruzzo, 19, have not been found.

Texas records show Camp Mystic had an emergency plan before floods killed at least 27 campers and counselors, but details of its storm response are still unclear.

For decades, Dick and Tweety Eastland presided over Camp Mystic with a kind of magisterial benevolence that alumni well past childhood still describe with awe.

A heartbreaking video shows campers and staffers at Camp Mystic being playful and enjoying their summer hours before waters from the catastrophic Texas flash flood swept away scores of young girls.
