A wildland fire caused by a storm in Sweetwater County last week has grown to more than 19 square miles, according to a news release from the U.S. Bureau of Land Management's Rock Springs field office.

The Laney Rim fire, about 25 miles south of Rock Springs, was detected on Saturday after a storm passed through the area on Friday night.

The storm also caused the Black Butte fire, which is contained, and the Big Ridge fire, which is currently under control. The combined weather conditions and fire activity meant that minimal resources were available for initial response to the Laney Rim fire.

Wednesday, 137 wildland firefighters were working to suppress the fire with most resources focused on the eastern edge where engines and other equipment can access the area. Sections of the fire are burning in steep, rocky, inaccessible terrain. Aviation resources are being used in these areas as needed.

Fire crews are focusing on keeping the fire east of Sweetwater County Road 27, south of Sweetwater County Road 32, west of Wyoming Highway 430 and north of Potter Mountain to minimize impacts to Priority Sage Grouse Habitat, oil and gas infrastructure, grazing allotments, and cultural resources.

The fire is currently burning on BLM, state and private lands,

No residential structures have been lost and no injuries related to the fire have been reported.

No evacuation orders or road closures are in place.

Two private structures at risk. Fire crews continue to monitor those areas closely.
