DEBRIS FLOW
The mass of jumbled gray rock has been deposited upon the red
rock by a violent and catastrophic event. Probably the result
of FLASH FLOOD, a mass of coarse boulders and smaller rocks have
been carried along and dumped in a chaotic pile. Flash floods
are extremely dangerous naturally occurring events in arid regions
where there is little vegetation cover to absorb and slow torrential
downpours of rain.
