(CBS4) – A small grass fire that was started by a vehicle broke out in northern Colorado near Livermore on Friday morning. Just after 10 a.m., officials with the Larimer County Sheriff’s Office said the grass fire was about 1 acre in size.

“It’s pretty dynamic up there. It’s not crazy, but it sounds like it’s moving,” sheriff’s spokesman Jered Kramer said.

The fire is near Highway 287 and Red Mountain Road.
