Firefighters worked to contain a 20-acre fire discovered Sunday afternoon Southern Ute Indian Tribe land just off County Road 500 in Archuleta County.
No structures were threatened by the Cat Fire on Sunday evening, said Pam Wilson, fire information officer with the Durango Interagency Fire Dispatch, in a news release issued Sunday evening. The fire was burning near a small parcel of private land.
Wilson said two single-engine air tankers, one heavy helicopter and one Type 2 crew and five to seven fire engines were fighting the blaze.
Also, Wilson said firefighters responded to several other smaller fires in Southwest Colorado and northern New Mexico on Sunday, including a single burning tree at the north end of Electra Lake.
