Firefighters have been dispatched to the Beach Fire, located in an area of alpine fir about two miles south of Beach Lake and seven miles west-southwest of the Bridge Bay Campground.
The fire is estimated at one-half acre. It is not known what started the fire.
Due to several factors including location, fuel, and weather conditions, firefighters are working to suppress the fire.
The fire danger in Yellowstone National Park is moderate. The National Weather Service is calling for warm daytime temperatures and isolated showers and thunderstorms with gusty winds into the early part of the week.
No roads, campgrounds, or trails are closed because of this fire. It poses no threat to visitors.
This is the fourth fire this year in Yellowstone. The Doane Fire, east of Yellowstone Lake and south of the East Entrance road, has been quiet for several days since it was discovered within the perimeter of the 2007 Columbine Fire on July 11. It remains one-quarter acre.
