DENVER -- The Red Rocks Trading Post is haunted, according to several employees who say they've simply gotten used to working with the supernatural.

"Every morning I'd just kind of greet them as I go down (the stairs). Just like, 'Hey guys it's just me, opening up the store. Don't worry about me,'" said Thomas Corbett, a four-year employee.

"It must be a special place for them," said Lori DeVey, another longtime employee.

The contention among staffers is that there are several ghosts, including a small child, inhabiting the Trading Post.

Built by Denver Mountain Parks as a city effort, the Indian Trading Post, as it was originally called, opened in 1931. It even included Native American wares from the Denver Art Museum.

There are stories, as chronicled in Tom "Dr. Colorado" Noel’s book "Sacred Stones: Colorado's Red Rocks and Amphitheatre," of a Hatchet Lady who would attack young couples enjoying the inspiring views a little too much.

The incredible amphitheatre itself was completed 10 years later and has become one of the world's most unique live venues.

"The dramatic sandstone monoliths serve as a history book of animal and plant life in the area for the past 250 million years," according to RedRocksOnline.com.

Employees said they know all of this history but feel many people don't know some of the more recent history, which they find fascinating as well.

"A lot of this happens when you're by yourself," DeVey said. "Usually, it's just getting dark. We all hear scratching, like dogs scratching on doorways. I found one employee just bawling one day. She said she heard a man's voice whisper her name, right into her ear. But when she wheeled around to look, there wasn't anyone there."

Many visitors are familiar with the layout of the current building. The front door opens to the gift shop area with the Java City coffee bar to the west, glassware and other gifts to the right.

One employee, Matt Corry, said even the main floor has seen unusual activity, such as porcelain cups found on the floor after the crew had locked up and left for the night.

"There used to be, like, coffee cups, Red Rocks coffee cups with names on them. And it was, I think it was Randy. But it was always the same name. And it just kept flying off the shelf," Corry said.

But it's downstairs where employees describe some of the strangest incidents.

"The boiler room -- it's the creepiest," Corry said.

With a sloping wall, the boiler room is one of several small, cramped rooms below the main floor where employees swear they've seen door handles shaking on their own.

The ice box is a tight, wooden room, big enough for three adults to stand inside. But the door is heavy, with a U-shaped lock and a door handle that is heavy and difficult for a young man to move.

Corbett said he watched that handle move and unlock by itself soon after he started working at the Trading Post in 2005.

It was enough that Corbett wanted to confirm or refute his fear that he was working alongside ghosts. So one night, in that same year, he left a digital voice recorder in one of the basement offices. Corbett said on that recording he heard voices, breathing, and boxes moving in a room that was empty, all night.

"It pretty much was what sold it for me," Corbett said. "I've got no problems. They ain't got no problems."

Ashley Jones recalls the encounter that convinced her the place was haunted.

"I was downstairs getting T-shirts and I had bent over because the boxes were on the bottom shelf and a box came flying at me. It didn't fall off the shelf. It was literally coming at me," Jones said.

TheDenverChannel talked with six current employees at the Trading Post about the alleged "ghost" tenants. All are convinced they exist there, yet none want the spirits removed.

"I've been working here four years now. I figure, if something was going to hurt me it would've done it by now," Corbett said.

"Downstairs you feel like someone's always right there behind you," DeVey said. "But I've gotten used to it now."

Employees said in past years, one staffer was so afraid he grabbed a handgun, another reached for a knife. No one has been hurt in any of the "incidents" and current staffers said they wouldn't have it any other way.

"I learned that there are more people that have stories than don't. It was really easy to find people who not only had a ghostly experience but that also wanted to talk about it and share their stories because they've accepted it as part of the culture at Red Rocks," said Jenny Schiavone, director of communications for Denver's Division of Theatres and Arenas. "It's not really surprising because it's such a spiritual place in general. I think it really is just a part of the mystique of that area."

Staffers said they will occasionally hear from shoppers who will ask if the Trading Post is haunted.

Several said they're happy to answer "yes."

But the stories aren’t always received well by skeptical family members.

"You know, people laugh and say, 'Oh, you're just hearing things,'" DeVey said.

Corry recalls seeing an old REO Speedwagon framed gold record fly off the wall near the coffee shop area. He said there was no wind and no open windows at the time.

DeVey said she's heard unexplained footsteps coming down the sloped ramp leading visitors from the main gift area to the glassware section.

"It was around 8:30 and I could hear walking up here on the ramp. And I could tell it was a heavier man with a longer stride. And then at the bottom of the ramp end, you could tell, it just kind of stopped. And then I could hear lighter walking all over the floor," DeVey said.

Several times, DeVey said she would come out of her office upstairs, on the second floor, to see who was tromping up the stairs toward her.

Each time, there was no one to see.

Corry describes coming back the building after a concert at Red Rocks to do payroll. It was summer in 2000 and he was all alone in one of the offices downstairs.

"And I mean, I'm sitting in there for about an hour. All of a sudden the room gets dead cold. I could see my breath. Cold. Cold. And I hear boots coming up. Thump, Thump. Right behind me. And I felt like just the cold hand going across, like my back. I got up and I was like, done," Corry said.

He still refers to the man he believes is haunting the place as "Boots."

There are stories of rock wind chimes clinking inside with no customers and no wind.

Bill Carle lived in the Trading Post building for four summers with his family operating it from 1963 to 2002 but doesn't remember ghosts.

"I lived there for a while and never saw or heard one," Carle said.
