Cache is set by the foundation of the tail house of the Red Jacket Mine. This is the only tail house I know of in the area so I don't know much about what was in it. Definition of a tail house: a housing for the tension carriage in an endless-rope mine hoisting system (Whiting system at the Jed Jacket)
Cache can be accessed from two locations. If you're doing the shaft cache, you can head north to the west of the hoist house ruins (pile of bricks). You will find an ATV trail which will bring you to the cache. If you're doing just this one, head north on N Tamarack Rd. Just before the road turns to gravel you'll find the other end of the ATV trail.
A series of disastrous underground fires in their mine on the Calumet Conglomerate Lode in the late 1880s prompted the Calumet and Hecla Mining Company to sink a new vertical shaft which would intersect the lode at depth. This new shaft was inspired by the success of the Tamarack Mining Company, who used the same methods to mine the conglomerate at great depths below their property nearby. C&H's Red Jacket Shaft was intended to provide "insurance" for the company, making the deepest areas of the mine accessible even if there was a fire in other sections of the mine - and it would provide underground workers an additional escape route. Construction began in 1889 on the shaft, just north of Calumet's Pine Street and continued for nine years before it was complete. The new six-compartment vertical shaft and its surface equipment was an engineering marvel. In 1896, this was the deepest mine shaft in the world at 4900 feet; two sub-shafts sunk below it at an incline brought the final depth to 9600 feet or nearly two miles. Due to the high cost of extracting ore at great depths, and the falling price of copper during the Great Depression, the last of the shafts operating on the Calumet Conglomerate was closed in 1939. By 1943, the great 8,000 horse power steam hoists and other machinery at Red Jacket Shaft had been removed in a World War II scrap drive. Most of the buildings on the surface were razed shortly thereafter. Today, a sandstone warehouse, once the auxiliary hoist house, remains standing near Calumet's Renaissance Road. The rest of the Red Jacket Shaft surface plant are ruins.
