In 1881, the Denver & Rio Grande Railroad arrived in Durango with a singular mission: extract the vast silver and gold reserves hidden in the San Juan Mountains
You are a Pinkerton detective, arriving in Durango, Colorado in the spring of 1882.
Your urgent task is to assist Otto Mears, a renowned mining engineer and road builder, in
Dive into the heart of 1880s Colorado, at the peak of the silver mining boom, where fortunes were made and lost to the rhythm of steam trains.
Your investigation begins at the Durango & Silverton Narrow Gauge Railroad Depot, located at 479 Main Ave. This railway line, completed in 1882, was the silver vein that connected Durango to the Silverton mines via a 914 mm narrow gauge. Between 1882 and 1920, it transported over 300,000 tons of silver and gold, solidifying Durango Colorado's status as a hub of the mining boom. The original 1882 depot is a testament to Narrow Gauge Railroad heritage, one of three narrow-gauge lines still operational in the United States, operated as a tourist attraction since 1947. Here you will find the first clues, hidden deep within this steel and steam giant that built the prosperity of the San Juan Mountains region.
Continue to the General Palmer Hotel, at 567 Main Avenue, built in 1886 by William Jackson Palmer, the very founder of Durango. This four-story Victorian building, named in his honor, houses an original lobby retaining architectural elements from the Colorado mining boom era. This is where silver barons and engineers like yourself met to seal crucial deals. The ambiance of Old West Colorado tourism still permeates the premises. Your path then leads you along Main Avenue, Durango's commercial heart since 1881. This thoroughfare, listed on the National Register of Historic Places in 1969, is lined with over 90 buildings dating from 1880-1910, preserving their original architecture. Its 36.6-meter width, designed for mining teams, offers a unique setting for your Durango visit.
Your journey takes you to the Strater Hotel, opened in 1887 by Henry Strater, a prosperous businessman from the mining era, at 699 Main Avenue. This five-story Victorian building houses a collection of over 10,000 Old West antiques. The Diamond Belle Saloon, dating from 1887, retains period decor that transports you directly into the Silver mining boom 1880s. Not far away, the First National Bank of Durango, founded in 1881, is a Romanesque Revival style building that financed major mining operations in the San Juan Mountains between 1881 and 1893. It survived the economic crash of 1893, a rare feat for the 500 American banks of the time, and its history is intrinsically linked to the history of Durango.
The Animas River, 154 km long, flows through Durango and was the main water source for 19th-century mining operations. Its Spanish name, meaning 'souls' or 'spirits', was given by 17th-century explorers. The Animas River Trail runs along the river for 4.8 km, offering a peaceful route for your Durango scavenger hunt. In August 2015, an accidental mine spill of 3 million gallons of contaminated water from the Animas Forks mine marked the river's modern history, recalling the environmental challenges of Colorado heritage. Further on, Smelter Mountain, overlooking Durango to the northwest, was the site of smelters processing 200 to 300 tons of ore per day between 1881 and 1920. The remains of the foundations are still visible, silent witnesses to this mining fervor.
Finally, your investigation leads you to Durango City Hall, built in 1892 in Romanesque Revival style, at 1407 East 2nd Avenue. Its 18.3-meter clock tower is visible from Main Avenue. This edifice, the continuous seat of local government for 132 years, represents Durango's longevity beyond the mining boom. By exploring this Colorado thematic circuit, you will have deciphered the city's secrets, from its railway origins to its Victorian architecture Colorado. This GPS scavenger hunt offers you an interactive Durango visit, a total immersion in the city's past, transforming each monument into a key element of your discovery. You will take with you not only the solution to the enigma, but also a deep understanding of this historic mining town, a true jewel of Colorado heritage.
