The spiral staircase ends in the basement, where two oil tanks (for the lantern) and a freshwater tank (for the Keeper) were stored. The basement consists of two long arched vaults like this.
Beautiful doors separated the boiler room and the sugar mill. Can you imagine the gracefully curving steps in a power plant today?
This is an elevator to move mine car loads of sand to the surface for cleaning and eventually glass production. Below is a flooded equipment vault. In front and behind is a loop through the larger tunnels in the mine. The horizontal braces supported electric cables for the mine carts.
If you look carefully along the side of the slip alongside this image of Cargill B-2, you will see the remains of the crane stops when this was a Hannah coal dock.

This ornamental stair is cast iron and used to connect all floors of the Administration building. Now it connects the first and second floor, then the third and fourth floors, with a strange cinder block and drywall barrier separating the new and old sections of the building. Note the insulation on the floor to seal heat into the lower floors that were used as offices until the hospital closed. On the corners of the staircase are lions, on the corners of the suspended section of stair are down-hanging pineapples. Set in the stairs themselves are shield motifs with slate tops.
Chester Creek, where it was forced to dip below the circa-1970s I-35 tunnels.
The basements of the barracks were often stone and brick, and many of them were connected by short tunnels.
Blast Furnace 7 as seen from the ore yard. Imagine running up those stairs through blast furnace smoke.
