Black Hills Energy spokeswoman Laurie Farkas told Townsquare Media shortly before 7 p.m that electricity had been restored to all customers hit by a multi-hour power outage late this afternoon.

The outage knocked out power to the Frontier Mall and Walmart, among other businesses. Traffic lights were not operational and businesses along the route of one of the city's main thoroughfares were forced to close. Farkas told Townsquare Media that a total of 1,239 customers were affected.

The cause of the outage was not apparent at first, and Farkas told Townsquare Media that crews had to scour the area to find the problem. But she said later that she understood the problem to be an underground line that was hit.

The outage was reported around 3:40 p.m., and power was fully restored a little over 4 hours later.

Meet the Four-Legged Heroes of the Cheyenne Police Department

They may not be able to leap tall buildings in a single bound, but make no bones about it, police dogs play a vital role in the fight against crime.

In many situations, they're the first ones to put their lives on the line to protect their human partners, proving that not all heroes wear capes, some wear fur coats.
