1999-2000 Photos - Passageways and Vertical Tower

Note that the bottom portion of the stair tower had been test assembled in McMurdo (C)...	Back at Pole, here is a closeup of the steel erection (C).
Here goes the first layer of the steel liner of the vertical tower. Behind it, the arch is moving closer to the tower (C).	The first bit of outer liner (corrugated aluminum siding) is being installed (FCA).
Looking from another angle, the dome is in the background (C).	Meanwhile, there was work going on inside the arches...we're looking toward the power plant and garage (FCA).
The connection of the arch and stair tower, on the outside (FCA)...	...and the inside (FCA).
Finish work in the power plant arch at the passageway toward the stair tower (RL).	The view from above. These 2 photos were taken on 21 January (RL).
Another look at the upwind end of the power plant arch (RL).	Another look toward the stair tower (RL).
The tower is topped out, temporarily, for the winter. To be continued (C)...
