ANCHORAGE - Chugach Electric Association is investigating the cause of a fire that burned a plastic ball marker on a Fort Richardson power line.
The flaming ball melted onto the ground around 11:30 a.m. Saturday, sparking a fire on the grass below the power line off the Glenn Highway, authorities said.
Anchorage Fire Department spokesman Tom Kempton said the fire was put out at 11:49 a.m.
There were no injuries.
Chugach spokesman Phil Steyer said the plastic balls are about the size of beach balls and serve as aviation markers. He said such fires are unusual but not unheard of.
There have been no outages from Saturday's fire, which occurred on a 115,000-volt transmission line near the National Guard Armory on the post, Steyer said.
The cause of the blaze is unknown, he said.
