National Mine and its rockhouse (?) as seen from Mammoth Hill. From this angle, I am fairly certain this was a crushing and sorting house. The bottom looks like it has two aerial tram doors as well.
A hydraulic ‘bridge’ couple lower onto the tracks to bring mine cars into the shaft house, presumably for repair. I haven’t found this system anywhere else, but it makes a lot of sense.
In the distance, the San Haven Sanatorium water tower.
This building would store and maintain warheads. It was right next to the launch pad, but the two were separated by a high mound.
The superstructure for the sea-leg skyways serves no purpose now… the offices are bricked up, too. Why?
A view of the hallway outside of the auditorium.
When I saw this section, I knew the dock was abandoned.
I am not sure, but I think this section was a storehouse; it has two ramps that connect the rail yard outside and the blacksmith shop. On all of the historic doors that face that part of the yard, signs caution workers to look out for cars…
The purpose of the concentrator was to separate the gold and silver-rich ore from the waste rock. You can tell from the design that the process relies heavily on gravity.
