More than an hour passed between Camp Mystic receiving a severe flood warning and a decision to evacuate young campers asleep in cabins by the Guadalupe River.

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

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.
