Photograph showing an arrastra cut into the rock at Buckskin Joe. Arrastras are pits cut into or lined with rock and used to crush ore by means of a drag stone pulled by a draft animal. The crushed ore was made into a slurry from which the metal was recovered. The mining camp of Buckskin Joe was located in Buckskin Gulch two miles west of Alma, Colorado in 1860. The camp had a population of over 1,000 in the first year, and during the first couple of years the placer mines produced $1.6 million in gold. By 1863 production had dropped and the town was mostly deserted.
