A wildfire straddling the southern Wyoming border spread by about a third on Monday, slowed by overcast skies and cooling temperatures.
The Ryan Fire, which was reported Saturday in Colorado’s Mount Zirkel Wilderness, had burned 2,470 acres by Tuesday morning. Firefighters had not yet achieved any containment, authorities said.
Two more fires are burning in western Wyoming’s Bridger-Teton National Forest. The Roosevelt and Marten fires had consumed at least 7,500 acres combined by Tuesday morning.
The Marten Fire began burning at about midnight Saturday, though few details were available Tuesday morning. It had consumed 3,500 acres about a dozen miles east of Afton.
Hunters reported the Roosevelt Fire on Saturday afternoon and by Tuesday afternoon it had burned about 5,000 acres. That fire had prompted some evacuations of subdivisions in the area including Rolling Thunder and Jim Bridger Estates.
The causes of the three fires had not been determined by Tuesday morning.
A handful of smaller fires are also burning in western Wyoming.
