The fire broke out around 10 a.m. in the Leavenworth and Platte County area. Officials said a spark from the Bureau of Prisons lawn mower started the fire.
In the blaze, a couple of older barns caught on fire, crews said.
The South Platte County Fire Department reported at least 1,300 acres have burned. More than 75 firefighters fought the fire.
Firefighters said the windy conditions on Wednesday made the response challenging.
"We tried multiple times to do some fire stops and work the fire lines," said South Platte firefighter Brian Richardson. "As soon as it would go down, it would jump up behind you."
The wind blew around smoke and debris, which presented even more challenges.
"With the wind, the way it was blowing, it was really tough to breathe at times," Richardson said.
Crews worked to prevent the fire from reaching the town of Beverly. Platte County deputies evacuated Woods Oil, a gas station on Highway 92, across the street from the massive fire.
"We could see a lot of flames," explained Cynthia Cunningham, who works at the store. "We saw some deer running for cover."
Cunningham said she was able to return to the convenience store about 90 minutes after she was evacuated from the area.
Fire crews also warned a homeowner down the road from Western Oil Co. about a possible evacuation.
"A deputy sheriff was at the door. He told us about the fire. He said there was a possibility that we would have to move out," explained Harry Schimmel, who lives at the home that was warned of the fire. "I was trying to think about where I'd go."
Crews also mowed the land and cut brush to help reduce the fire danger in the area. They said the fire was 75 percent contained at about 4:45 p.m. and was finally fully contained before 6 p.m.
Fire is under control. Crews are continuing to put out smaller fire areas.
