Not a lot has changed since the last update. Warmer, humid weather and winds over the next couple of days will continue to dry fuels, which may result in increasing fire behavior (creeping, isolated/small group torching), but is not likely to cause large fire growth. Fire is a natural part of the Yellowstone ecosystem, consuming dead wood and logs, cleaning fuels from the forest floor and reducing the likelihood of a future, catastrophic fire that could occur when conditions are extremely dry. The Maple Fire continues to be monitored. Intermittent smoke and possible flames may be visible over the next few weeks, as the fire will continue to creep and smolder through dense duff and large logs.

What’s Open:

  • All entrances to Yellowstone National Park are open.
  • Park visitor centers, concession-operated services, and businesses in surrounding communities are open.
  • The road into Slough Creek is open for the first half mile only (to the gravel pit) for fishing access.
