Some camps in the region had to be evacuated, and local newspapers described how Camp Mystic was among those cut off from the outside world. According to a Kerr County history book, floodwaters at Camp Mystic almost reached the top of the dining hall’s stairs.

Dick Eastland, the Camp Mystic owner who pushed for flood alerts on the Guadalupe River, was killed in last week’s deadly surge.

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