shadow

It is an awesome weather and I think the shadow I found on the site is quite interesting. I think shadow is a good indicator to show time changing in daytime. No matter the direction of the shadow changing or the pattern of the shadow changing amazed me a lot.

Something will happen at some specific time , for instance, traffic is busy sometimes at some specific time and it is not so busy at other time. And shadow is a natural indicator to show the time changing. Just like the sundial that ancient people used to record time.

Also, this picture I took on the site:

I am assuming that the shadow of the polar will continuously change its direction according to the sun moving in the daytime. And the changing shadow which means the changing time maybe tied to some events on the site, say when the traffic is busy or not.

Below are the busy time and less busy time of the traffic, and I am assuming that it could related to the different time which could be indicated by shadow. And shadow of the overpass could also change according to the different time in the daytime.
