This picture shows the 100 Central Building side that faces 1st St. Note the shadow on the building. This is the shadow of the Five Points Plaza Building. The picture was take at 1:30 in the afternoon on Jan 26.
It is apparent that the sun will never shine on the surface of 1st St on this block during the winter months.
The next picture shows the view east on 1st St at the same time. No sun, only shadow. Just like a canyon.
The final picture shows the opposite view down 1st St - looking west. Lots of sunshine and dappled shade under the oaks.
