With more than 100 people dead, many of them children attending a Christian summer camp on the banks of the Guadalupe River, Friday's extreme flash flooding that overwhelmed a sizeable chunk of central Texas will be recorded as one of the state's worst ever natural disasters.

The brunt of the tragedy was felt in Kerr county, where at least 27 children and counsellors were killed after a deluge of water described by one witness as a a pitch-black wall of death" swept through the all-girl Camp Mystic on the river's south fork. About 750 young campers were celebrating the Fourth of July holiday.
