It looked like something out of “Charlie & the Chocolate Factory.”
A couple miles of deeply-puddled 4WD road ended in a sizable pour-off which was disgorging the contents of the thunderstorm. After a 140-foot free-fall, the muddy waters were extruded from the collecting pool into a ribbon that followed gravity into Courthouse Wash and eventually into the mighty Colorado River… which would be flowing intensely red that day. I love the summer monsoons.
