SOUTH SALT LAKE — A field fire along the Jordan Parkway took about 40 minutes for crews to put out this morning but did not seriously threaten any structures.

About 10 a.m. a field fire was reported along the parkway near 3900 South. When fire crews arrived, the blaze was going fairly strong, said Unified Fire Authority Capt. Jay Fearnley.

Some nearby power lines were threatened but were not damaged. About 15 field firefighters from UFA, South Salt Lake, West Valley City and Murray helped extinguish the flames.

The cause of the fire was still being investigated Wednesday afternoon. Fearnley said there had been a couple of fires in the same area over the past week or two, and it was unknown if something had been smoldering and went undetected.
