DEADWOOD, S.D. (AP) -- A heavy thunderstorm caused a mudslide in Deadwood early Thursday evening.
The mud, more than a foot deep in some areas, prompted the closure of some streets for several hours. The mud and debris that came into the town are said to be runoff from the Grizzly Gulch fire, which burned much of the vegetation in the area in late June and early July.
The National Weather Service said more than an inch of rain fell in about 20 minutes.
There was some property damage but no reports of any injuries, said Deadwood Fire Department spokesman Scott Randolph.
More than 150 state prison inmates have been sent to assist in the cleanup, the Department of Corrections said.
For many in Deadwood, the floods were not completely unexpected. But the speed and severity of the flash floods was a surprise.
Anotone and Beata Schwindt lost their garage to the Grizzly Gulch fire and are now scooping mud out of their basement. They said they hope to save their furnace.

"We were just standing outside, watching the storm and all of the sudden I told my husband to come and look ... it was moving right at us," Beata Schwindt said.
Local business owners who witnessed the flooding said it was unlike anything they had seen.
"It was just scary. It didn't rain but five minutes and down the street it came," said Loray Bauer, the owner of Pack Horse. "Business owners were holding their doors shut to keep the mud out."
At Whistler's Gulch, where a campground lay in the path of run-off, mud was one to two feet deep along the side of the lodge building after fewer than five minutes of rain, said Deadwood Police Chief Dan DeNeire.
"It was lots of ash along with mud," DeNeire said. "It was totally black, running off over the fence and into the creek."
DeNeire said he was surprised the flooding happened so fast.
"I thought if something like this, the flooding, was going to happen, it would happen after an hour or so of rain, not just in 15 minutes or so," he said.
