The Mystery of the Dome on the Range Near Cheyenne Wyoming Explained

If you have spent any time driving west of Cheyenne on Interstate 80, you have likely spotted a curious, weathered dome sitting alone in a field. According to reports from K2 Radio, that structure is actually an original 1917 copper and concrete cupola salvaged from the Wyoming State Capitol building during roof renovations in 1999.

The Journey of the Dome on the Range

The structure has gained a second life as an internet curiosity, with social media users frequently sharing memes featuring the dome. One viral Photoshop edit even depicted the legs of the Wicked Witch of the West protruding from beneath the heavy, circular relic. Despite its current status as a roadside oddity, the piece of history has a documented, if somewhat unconventional, provenance.

After being removed from the Capitol’s House or Senate chamber wings nearly three decades ago, the cupola was purchased by a salvage yard for a mere $100. The buyer, Dan Corbin, initially kept the piece on his own property as a yard decoration. However, following complaints from neighbors regarding the aesthetic impact of the massive, decaying structure, it was relocated to its current resting place near the historic 1892 Granite School.

Locating the Historic Cupola

For those looking to see the artifact in person, it remains visible from the highway. Travelers heading west on Interstate 80 can spot the dome on the left side of the road, situated in a field adjacent to the abandoned schoolhouse in Granite. The site is located approximately 22 miles southwest of Cheyenne, accessible via Exit 342.

Time has not been kind to the structure. Exposed to the harsh Wyoming elements for over 25 years, the copper and concrete are showing significant signs of wear. The schoolhouse sitting next to it shares this weathered, forgotten appearance, marking a stark contrast to the manicured grounds of the active Capitol building where the dome once stood.

While this cupola has found a permanent, albeit quiet, home, the mystery of its sibling remains unsolved. Documentation indicates that a second, identical dome was also removed from the Capitol during the same 1999 renovation project. Unlike the one sitting off Exit 342, the location of that second piece remains entirely unknown. Whether it was scrapped, repurposed in a private garden, or simply lost to time is a question that continues to linger for local history enthusiasts.
