SHAWNEE COUNTY – Fire crews continue to monitor areas of a large, weekend grass fire in Shawnee County, just east of Topeka.

The blaze started just before noon on Sunday and jumped Interstate 70 near Carlson Road and moved north rapidly threatening multiple structures, according to a social media report from Shawnee County Fire.

The fire stretched an estimated 4,000 acres and required resources from approximately 30 agencies and four counties to extinguish.

No injuries were reported and no buildings damaged. The fire was largely declared extinguished just before 6:30 p.m. on Sunday.

The fire is believed to have started as the result of a flare-up of another grass fire on Saturday, according to Shawnee County officials.
