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

Katherine Ferruzzo, a Camp Mystic counselor who had been missing since the Texas floods, was found dead on Friday, July 11, Ferruzzo's family confirmed in a statement obtained by NBC 5.

Almost a week has passed since fast-moving floodwaters tore through the Texas Hill Country during the early morning hours of July 4, submerging roads, sweeping away structures, and turning the usually peaceful Guadalupe River into a deadly force.
