(Gunnison-AP) -- Crews are working Sunday to build fire line around a 165-acre wildfire burning 13 miles southeast of Gunnison.

The lightning-sparked fire started Friday but four air tankers dropping retardant helped slow the spread of the fire.

The fire is 90 percent contained and firefighters hope to have the last stretches of containment line dug by Monday.

Also on the Western Slope, another lightning-sparked blaze about six miles east of Egnar was contained after burning about 55 acres.
