Officials are trying to figure out what sparked a late morning fire at the Sierra Trading Post Fulfillment Center Monday.

Cheyenne Fire Rescue spokesman Scott Smith says​ firefighters were called to the warehouse shortly after 10 a.m. and had the fire under control in about 30 minutes.

Smith says the facility's sprinkler system gave firefighters an edge in knocking down the fire and keeping it from spreading.

He says the building sustained water and smoke damage, but he didn't have a damage estimate.

Fortunately, everyone in the building was able to get out safely.
