A fire in Yellow Jacket Canyon southwest of Lewis on Monday reached 395 acres.
The blaze, dubbed the Yellow Jacket Fire, was burning on private land and partially on Canyons of the Ancients National Monument. It is west of the intersection of County Roads 19 and V and is near farms. The fire was growing, but no structures or residences were threatened, Montezuma County Sheriff Steve Nowlin said Sunday.
As of 10 p.m. Sunday, the fire was at 378 acres, up from 80 acres at 6:15 p.m., according to the Durango Interagency Fire Dispatch. Lightning from a storm Saturday night was the suspected cause.
Smoke from the fire, northwest of Cortez, was reported about 1 p.m. A rising plume of smoke was visible from Cortez, Dolores and Dove Creek.
BLM, San Juan National Forest and local firefighting departments are responding to the scene, and the strategy is full suppression.
