What the National Weather Service wrote

A major flash flood roared down from the west slope of the Animas River Valley across the Durango and Silverton Narrow Gauge Railroad and into the Animas River. The flash flood deposited mud, boulders, and pine trees up to 15 feet deep onto a 300 foot section of railroad tracks. The Animas River was also clogged from the debris. It took 6 days for crews to clear the debris and repair the railroad tracks before the railroad could reopen.
