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.

As hope for finding survivors dims, questions swirl around whether Camp Mystic's emergency plan was adequate. Texas doesn't approve or keep copies of such plans; camps are required to show only that they have plans in place.
