Firefighters from Clay and Wichita counties battled a large grassfire southwest of Henrietta on Monday.
The fire was first reported at about 11:15 a.m. The fire spread rapidly due to warm temperatures and dry conditions, burning an estimated 300 acres. Temperatures reached 92 degrees with winds from the southeast at 14 miles-per-hour.
A Henrietta volunteer firefighter was treated on site after he was overcome by heat.
The fire started in a pasture on the Bolin Ranch near F.M. 2606, north of Lake Arrowhead, and spread northwest to the west fork of the Little Wichita River. Cause of the blaze is unknown.
Volunteer fire departments from Henrietta, Jolly, Bluegrove, Lake Arrowhead, Arrowhead Ranch Estates and Wichita East, as well as a task force from the Wichita Falls Fire Department, responded to the blaze.
Rough terrain and thick mesquites hampered efforts to control the fire. Two Henrietta dozer services also responded, cutting fire breaks around the blaze.
