Coco Grieshaber, an 8-year-old Camp Mystic alumna, threaded beads into a homemade bracelet at her dining room table, sharing memories of the Texas summer camp that she left four days before flooding devastated the area on Fourth of July weekend.

The leader of Camp Mystic had been tracking the weather before the deadly Texas floods, but it is now unclear whether he saw an urgent warning from the National Weather Service that had triggered an emergency alert to phones in the area, a spokesman for camp’s operators said Wednesday.

Maps show how heavy rainfall and rocky terrain helped create the devastating Texas floods that have killed more than 120 people.
