56-year-old James Bradley Meinert, a resident of Virgin, Utah, was trimming trees from a hoist bucket about 25 feet above the ground when the equipment became entangled in high-power lines.
The accident occurred in Brookside, about 20 miles north of St. George.
Emergency personnel were slowed in their response both by the remoteness of the area and the fear that the tangled power lines were still alive with as much as 39,000 volts of electricity.
Crews from Rocky Mountain Power arrived to confirm the lines were safe to work around. Meinert's body was retrieved from the bucket, but efforts to resuscitate him proved unsuccessful.
