Both fires are located on the east slopes of Mount Washburn, and are well east of the road linking Canyon Village, Tower Fall, and Roosevelt Lodge.
The Lookout Fire, when discovered Tuesday afternoon, was confined to a single tree in the backcountry southeast of Dunraven Pass.
The Antelope Fire is located northeast of Dunraven Pass, in the backcountry near Antelope Creek. At times this fire is producing a small smoke column which is visible on the Mt. Washburn Fire Lookout Web Cam. The size of the fire has not yet been estimated.
The two fires are believed to have been started by lightning. No roads, campgrounds, or trails are closed because of either fire. They pose no threat to visitors.
There have been 11 fires in Yellowstone National Park this year. The largest of the year was the Beach Fire southwest of Bridge Bay Campground, which was contained at 520 acres.
