Historic Flooding Closes Yellowstone National Park, Montana Roadways

June 13, 2022

Reports of flooding across the state continue to develop, most recently in Park County and at the northern gate of Yellowstone National Park. All inbound traffic to Yellowstone is closed.

Over the past 2 days, a meteorological phenomenon called an “atmospheric river” brought 200-300% of Montana’s normal amount of moisture. Combined with a heavy snowpack above normal, snow melt and rains are pushing rivers and streams to record volumes. Gear Junkie
