Texas parents frantically posted photos of their young daughters on social media with pleas for information as at least 23 campers from an all-girls summer camp were unaccounted for after floods tore through the state’s south-central region overnight.

The first photos from flood-ravaged Camp Mystic, the Christian Texas summer camp from which 27 young girls are missing, tell a heartbreaking story. The images capture both the destruction of the floodwaters—toppled trees and shredded buildings—but also the human traces left behind by the campers.
