Inside the park is also a placement of an abandoned mine Molybdenite, an interesting example of industrial archeology.
Important deposits include the disseminated porphyry molybdenum deposits at Questa, New Mexico and the Henderson and Climax mines in Colorado.
The prospector Charles Senter discovered and claimed the outcropping of molybdenite (molybdenum sulfide) veins in 1879, during the Leadville, Colorado, Silver Boom, but he had no idea what the mineral he found was.
