SALT LAKE CITY (AP) — A Utah wildfire that destroyed 52 homes and left one man dead was caused by arcing between power transmission lines that were built too closely together and sent a surge to the ground that ignited dry grass, a fire investigator said Wednesday.

The central Utah Wood Hollow Fire began June 23 and wasn’t fully contained for 10 days, costing nearly $4 million to fight, according to state officials. Officials said 160 structures total were destroyed.
