“One of the nation’s more unusual art spaces can be found off a well maintained gravel road outside Spearfish, in a geodesic dome festooned with fantastical globes.”

The New York Times

“Standing in the Termesphere Gallery, celestial artwork slowly circulating above my head, I find standard vocabulary woefully inadequate and flat.”

Helene Sorcic, Splash Magazine

Aerial view of the four geodesic domes on Christensen Drive

The property on Christensen Drive, Spearfish, South Dakota. Four domes, built one at a time over fifty years.

1972

The First Dome

After meeting Buckminster Fuller at Black Hills State University, Dick built his first geodesic dome on family land outside Spearfish. He intended it as a place to store work. Instead, he moved in. Markie moved in too, and they have been here since.

Early 1980s

The $100 Dome

A neighbor named Tom Monahan had built a dome in Sturgis but never finished it. Dick bought it for $100, disassembled it piece by piece, hauled it over, and rebuilt it next to the first. He built a small path connecting the two.

1984

The Studio

A commission for a seven-and-a-half foot sphere gave Dick and Markie enough money to build a proper studio dome. Dick still works in the upper half today. The lower half was Markie's puppet studio for years, and is now the Turtle House, one of two Airbnb stays on the property.

1992

The Gallery

The gallery dome was built in 1992. Lang and Kabe, Dick's two sons, pressed their handprints into the wet cement that year. The dome holds the world's only permanent collection of Termespheres, all hanging from motors, all slowly turning.

"This was an amazing rare find! My husband and I and two twenty-year olds were looking for something to do for a couple hours while in Spearfish. The weather was impacting our plans so we were seeking indoor things to explore. So glad we found this place."

"What a great place! We had no idea what to expect going in, but Lynn welcomed us and did an outstanding job introducing us to the artist's works. She seemed really passionate, knowledgeable, and friendly. My kids really enjoyed it too."

"This is the neatest place! Truly a Black Hills hidden gem that is easily missed. I could spend hours here! There is so much to see, and no matter how long I look, I always find something I didn't see before. This place quickly made it to my must-see list."

Stay at the Gallery

Two geodesic dome stays, right on the property.

The Turtle House at the Termesphere Gallery

The Turtle House

A fully renovated geodesic dome at the base of Dick’s studio. The lower level has been transformed into a comfortable stay with its own entrance, kitchen, and living space, all surrounded by the Black Hills. This is where the work happens above you and the pines are right outside the door.

The iCasa at the Termesphere Gallery

The iCasa

A small geodesic dome on the hill above the property, set among the ponderosa pines with views across the Black Hills. A loft bed, a deck, and the kind of quiet that doesn’t exist in most places. More glamping than lodging, and that’s exactly the point.
