Young campers and a dad saving his family were among the dozens killed in the historic flash floods that tore through central Texas over the holiday weekend.

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.

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