Up and Down (One step at a time)

Selena, nut, has been out to "do the stairs" several times already. 17 floors. Whee.

She did not notice however that the tops of each stairwell have a floor-to-ceiling glass window beside each (locked) door to the roof. You see mostly roof; but you get a pretty good view of the horizon too, in nearly all directions except north-east.

The top image is obvious; the middle is looking towards Niagra/Hamilton; the bottom is mostly west, you can see the Niagra escarpment slightly glowing in the distance.
