Silver Valley — Decode the Lost Vein
You are a determined mining prospector, in Wallace, Idaho, 1981, on the trail of the legendary Lost Vein.
Your mission: decipher the clues left by the
Dive into the heart of Wallace, the "Silver Capital of the World," to uncover the buried secrets of Silver Valley, where silver forged a history of labor and fortune.
The story that haunts this land
Your quest begins at the Wallace District Mining Museum, opened in 2000 and dedicated to the mining history of the Coeur d'Alene district. This site, located at 509 Cedar St, is your first point of contact with the past of Silver Valley's silver mines, exploited since 1884. The artifacts and exhibitions prepare you to understand the scale of mining that made Wallace, Idaho, famous, a city at the heart of the Historic Mining District. It is here that the legends of the miners begin to unfold, laying the groundwork for your scavenger hunt through the "Silver Capital of the World."
Continue your exploration to the Northern Pacific Depot Railroad Museum, a historic railway depot built in 1901 by the Northern Pacific Railroad. This building is an integral part of app-guided treasure hunts in Wallace, located along the downtown walking path near Burke Canyon Road. It testifies to the crucial importance of rail transport for shipping silver extracted from Idaho's mines. This historic site is a key step in understanding how Wallace prospered, connecting the miners' labor to national markets.
At the heart of your journey, discover the Center of the Universe Manhole, a manhole cover declared 'Center of the Universe' by the city in 2004. This iconic spot is included in the 1.71 km walking scavenger hunt in historic downtown Wallace and is part of photo challenges and riddles on local tourist routes. This curiosity illustrates the unique spirit of Wallace, a city that, despite its size, has managed to mark its territory with a unique sense of humor, while remaining deeply rooted in its identity as the "Silver Capital of the World."
Your itinerary then leads you to the legacy of the Sierra Silver Mine, an active silver mine until 1981. Since then, it has offered underground tours with retired miner guides. These 75-minute tours, where the temperature is 50°F (10°C), depart every 30 minutes during the season. Accessible via a historic trolley from downtown, this mine offers 40 minutes underground, a direct immersion into the working conditions of the miners who shaped Wallace's history. It's an opportunity to connect with the stories of these men and understand Idaho's mining heritage.
At the end of the route, you will have climbed the South Hill Stairs, historic stairs connecting downtown to South Hill, a secret local shortcut revealing mining history with each step. Included in photo challenges, these stairs are an integral part of Wallace's historic district, a mining hub since 1884. This walking tour will have allowed you to grasp the spirit of the Historic Mining District, from its buildings like the Shoshone County Courthouse (official starting point for scavenger hunts) to the free 4-acre outdoor Mining Heritage Exhibition by the river. You will take away a deep understanding of Wallace, the "Silver Capital of the World," and its role in Idaho's mining history.
