Bridges

I recently wrote about a walk we took the other day and mentioned that I had a bit of an adventure. The water surrounding the bridge support on the left (which I called an abutment but which I’m not sure isn’t more correctly a cutwater) doesn’t look all that deep, does it? I can tell you, from very personal experience, that it is. Or, at least it was deep enough to saturate me to the armpits as I made my way to the cutwater itself. Do not worry, my camera pack was well above my head during the traverse. At first I was going to post the image alone and then Joanna observed that the photo of the fallen log, taken just a few minutes after my swim, was also an image of a bridge. As part of the Pine Creek Rail Trail the steel truss crossing allows hikers, walkers, bicyclers, and runners to move from one side of the creek to the other. As for the bridge on the right, I can imagine any number of creatures, small and not-so-small, taking advantage of the placement of the log to negotiate the distance across the water. If you look closely, you may note that these images have something else in common. Both provide nice examples of specular reflection such that you can see the bridge, trees, and sky reflected in the water in the image on the left, and trees and sky in the image to the right. Interestingly, both also demonstrate what happens when the direct rays of the sun are blocked and objects are then illuminated by incidental light. This has a somewhat disorienting effect, making the viewer question points of spatial reference.
