Satellite imagery of Camp Mystic and other areas along the Guadalupe River shows the devastating aftermath of the Fourth of July floods in Texas.

Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

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.
