A wildfire at Custer State Park in the Black Hills of South Dakota has spread without causing any injuries.

Lydia Austin, a park spokeswoman, said Tuesday afternoon that the fire has grown to more than 6.25 square miles (16.2 square kilometers). That's up from more than 4.6 square miles (11.9 sq. km) reported that morning.

One unused building has burned down, but no one has been injured. Kobee Stalder, the park's visitor services program manager, tells KELO-AM that firefighters have concentrated on protecting structures including the Blue Bell Lodge and the State Game Lodge.

Stalder says people can "tip our hats" to firefighters, saying he's confident the buildings won't be lost.

The blaze erupted Monday during dry, warm weather. Austin has said the cause is under investigation.
