Yellowstone National Park has temporarily closed access to Boiling River, a popular watering hole just north of Mammoth Hot Springs.
According to a Yellowstone press release, warm weather has created muddy trail conditions, making it unsafe for visitors to trek down to the site. In addition to deep mud, there is also standing water.
The trail will remain closed until further notice.
As the name implies, Boiling River is unseasonably warm due to runoff from Yellowstone’s thermal features. It’s a destination for soakers in both summer and winter.
Yellowstone occasionally closes access to Boiling River when conditions are rough. For instance, the park temporarily closed access for part of June 2016 when the streamflow rate was deemed too dangerous for soakers.
