The historic Mammoth Hot Springs Hotel in Yellowstone National Park will reopen for the winter season after being shuttered all summer.

The facility had to close after the North Entrance road was washed out by the Gardner River during high water in mid-June. Buried alongside the road was a sewer line that carried wastewater from Mammoth to the nearby Gardiner sewage treatment plant. Thousands of gallons of raw sewage flowed into the Gardner River for about a day-and-a-half when the pipe was ruptured.

Park crews eventually rerouted the wastewater into old percolator ponds used from the 1930s to 1960s, enabling Mammoth residents and workers to stay throughout the summer.
