September 1878
You are an assistant to Grenville M.
Dodge, the Union Pacific engineer, dispatched to Cheyenne in 1867 to help secure the new railway line and investigate the region's complex history
Dive into the founding epic of Cheyenne, a city forged by rail and the gold rush, where every Wyoming cobblestone whispers the secrets of the Wild West.
Your journey begins in front of the Cheyenne Depot Museum, an 1884 building that served as the main Union Pacific Railroad station. Restored in 2003, this railway museum at 121 West 15th Street is the heart of Cheyenne's historic center, founded in 1867. It was here that pioneers converged during the 1868-1869 gold rush, marking the beginning of Wyoming's expansion. The museum houses a collection of artifacts and locomotives dating back to 1867, testaments to the golden age of the railroad and the city's genesis.
A short walk away, the Cheyenne Civic Center Park, opened in 1975 at 200 West 17th Street, offers a green contrast. This 2-hectare urban park, adjacent to the Depot Museum, is a central space for Cheyenne residents. It hosts annual events like the famous Frontier Days since 1897, a tradition that anchors the city in its Western identity. Its immediate proximity to the Wyoming State Capitol, less than 500m away, highlights its role in the civic and historical life of Wyoming's capital.
Continue to the Wyoming State Capitol, an iconic monument built between 1886 and 1890, with an extension in 1915, located at 200 West 24th Street. Its 30m high copper dome is an architectural landmark of Wyoming. Seat of the state government since 1890, this building was listed on the National Register of Historic Places in 1969. 800m on foot from the Depot Museum via historic streets, it embodies institutional permanence in the heart of this pioneer city.
The route then leads you to the Historic Governors' Mansion, built in 1904 and located at 300 East 21st Street. This official residence for governors until 1976, in Georgian colonial style with 28 rooms, was restored as a museum in 1988. Thirteen governors resided there, including the first pioneers of Cheyenne as early as 1869. 1km from the Depot Museum, in the historic governors' district, this site takes you through the eras and figures who led Wyoming. Not far, The Historic Plains Hotel, opened in 1911 at 1600 Central Avenue, is a 5-story Beaux-Arts luxury hotel. Listed on the National Register of Historic Places in 1978, it is 700m from the Depot Museum.
Your exploration concludes at the First Presbyterian Church, consecrated in 1885 at 202 East 18th Street. Cheyenne's first church, its Victorian Gothic style and 40m tower were the work of the 1869 pioneers. Listed on the National Register of Historic Places in 1972, it is 500m from the Depot Museum. This journey through Cheyenne, dotted with sites listed on the National Register of Historic Places USA, offers a deep understanding of the Union Pacific Railroad Heritage and the Cheyenne Historic District, revealing how the decisions of 1867 shaped Wyoming's heritage and its unique identity.
Your exploration of Cheyenne will have immersed you in the heart of a unique heritage, that of the National Register of Historic Places USA. From the Union Pacific Railroad Heritage rails to the heart of the Cheyenne Historic District, you have followed in the footsteps of the 1867 pioneers. Each building, from the Cheyenne Depot Museum to the First Presbyterian Church, tells a facet of Wyoming's history, a story of perseverance and construction. You carry with you the narrative of a city born of audacity, where the echo of the gold rush still resonates in the streets. This is a complete immersion into the soul of Cheyenne that you have experienced.

You arrive in Cheyenne, Wyoming, open the link on your phone, the story starts. It's the modern outdoor escape game: audio narration, camera puzzles, final code unlocked as a team. No install. No need to book a time slot.
Of course. Stop at a café, have lunch, resume later: your progress is saved. Many players bake a meal break into the trail, especially with families.
No, solo works very well. The outdoor escape game format in self-guided mode leaves room for introspection: read the story at your pace, hunt clues like a detective. 2-6 players is more social, solo is more contemplative.
Spring and autumn are the best seasons: mild temperatures, fewer tourists, gorgeous light. Summer is also great but go for early morning before 11 or late afternoon. Winter is perfectly playable, especially in southern cities — Cheyenne, Wyoming often feels more authentic then.
