Winds gusting up to 50 mph along the Front Range and eastern plains fanned flames that spread out quickly across 7,100 acres - or 11 square miles - of grassland near Ordway and forced the evacuation of all of its 1,200 residents. At least 20 buildings - including four within town limits- were damaged, fire information officer Chris Sorensen said. That fire was 50 percent contained by late Tuesday.
Two people died in that blaze, though officials haven't released details.
A single-engine air tanker crashed, killing the pilot, who was battling a blaze at Fort Carson that had scorched 9,000 acres - about 14 square miles - and forced the evacuation of people living near the base. Firefighters were unable to get any part of that blaze contained by late last night, base spokesman Capt. Gregory Dorman said. Two shelters were set up at the post and another at a nearby community college to house the evacuees.
The name of the pilot has not been released.

In Ordway, the darkened town without electricity stood deserted as smoke hung like fog late Tuesday with all but a handful of residents having left town for the nearby communities of Sugar City and Crowley, where officials set up a shelter. An unknown number of residents were allowed to remain in a nursing care facility in a section of Ordway not threatened by the fire, Sorensen said.
Brian Walker, 45, stood ready to save his house from the flames armed with a chainsaw, a shovel, and a water hose.
"Well, I got a yard, and I got a home and I want to keep it," he said. "I thought if the fire came, I thought I could do whatever I could to stop it."
