The youngest girls at Camp Mystic in Texas were asleep in cabins as little as 225 feet from the river when flash flooding suddenly surged — causing the water to rise 20 feet above flood stage in just 90 minutes, starting around 4 a.m. on July 4.

Along the Guadalupe River and just miles south of the unincorporated community of Hunt, population 1,300, sits Camp Mystic. The private Christian summer camp has hosted generations of Texas girls for almost a century.

Search and rescue continue for 20 missing campers at flood-hit Camp Mystic, with Lt. Gov. Patrick urging prayers.
