Not far from the Diamond Tunnel is the Eureka Croesus Mine, also known as the California Tunnel. Set up in the 1870s (in the early days of the mining district), it was never a large operation but is interesting today because of the equipment left behind.
A double drum hoist and duplex air compressor sit idle inside the hoist house. It is interesting to see them still in place after all these years, but even more so when you note that they were steam-powered. It’s rare to find early-day steam-powered equipment anymore. These are old indeed. The boiler and all the other equipment used in the works have long since been removed, which is a shame.
The Eureka Croesus portal is caved. The shaft here is also in poor ground and unstable.
