Investigators have determined the cause of a fire at a cabin on Casper Mountain earlier this week.

The Natrona County Fire District says electrical failure in the wiring, is what caused the fire that started just before 2:30 am on Tuesday, December 20th.

The cabin was located near the Treehouse Restaurant near the turnoff to Hogadon Ski Area.

A passing motorist spotted the fire first, and contacted fire fighting crews.

No one was home at the time, and no injuries were reported.
