Idaho City — The Lost Prospector's Treasure
You are Moses Splawn, sheriff and miner in Idaho City, 1867.
Your task is to solve the mysterious disappearance of a prospector. Your quest begins at the Boise Basin Museum,
Dive into the fervor of the Boise Basin gold rush, following in the footsteps of the prospectors who shaped Idaho in 1862.
The story that haunts this land
Your investigation begins at the Boise Basin Museum, located at 110 Main St, a 7m x 10m wooden building typical of Victorian mining architecture. This site, built in 1864, was the town's first public school before being restored in 1975 by the local historical society. It is here that material testimonies of the Boise Basin gold rush, which peaked between 1862 and 1864, are preserved. The artifacts provide insight into the living conditions of the pioneers and the challenges they faced, laying the groundwork for your investigation into the prospector's disappearance.
Continuing your journey, you reach the Boise County Courthouse, built in 1867. This two-story brick building, measuring 20m x 15m, is Idaho's oldest continuously operating courthouse. It has been the seat of Boise County since 1864 and was the scene of sensational trials during the gold rush. Court records from that era include cases involving Chinese miners, reflecting the tensions and social realities of this intense period in Idaho's history. The walls of this courthouse have witnessed hundreds of destinies linked to fortune and justice.
Your path then leads you to the Idaho City Cemetery, opened in 1863 and located 0.8 km from the center. This main cemetery contains over 700 graves of pioneers and miners, offering a somber but essential perspective on life and death in Idaho City. Specific sections are dedicated to Chinese miners from the 1860s and victims of the great fires that ravaged the city in 1865 and 1866. Each tombstone tells, in its own way, a part of local history, a poignant reminder of the sacrifices and hopes of that era.
Further on, 1.2 km from the Boise Basin Museum, you discover the Idaho City Chinese Cemetery, established around 1870. This site, linked to Chinese mining history, contains over 200 anonymous graves. The Chinese community represented 20-30% of Idaho City's population in 1870, and Taoist funeral rites were observed there until 1900. The presence of these distinct cemeteries testifies to the cultural diversity and integration challenges faced by different communities during the gold rush, highlighting an often-overlooked facet of Idaho's heritage.
Your investigation concludes by exploring Main Street, Idaho City's main thoroughfare since 1862 and the heart of the National Register of Historic Places (NRHP 1972) district. Over 1.5 km, this street is home to more than 50 historic buildings dating from 1864 to 1870, including the Odd Fellows Hall, built of brick in 1866 and having survived the great fires. This 3-story, 12m high building served as a mining meeting hall. By walking this street, you perceive the lasting imprint of the gold rush, a legacy that shaped not only Idaho City but also the entire Idaho Historic Site, offering a complete immersion in the history of this territory.
