River Wall
While playing around on Google Maps recently, I followed the course of a river from its headwaters to its outlet in Hudson's Bay. I noticed that as I followed it's course it was abruptly cut off by a dam... and it was cut off a half-dozen more times by similar dams. Dams from the air look funny: they cut off the beautiful fractaline/neuronal shape of the river making it abstract. Below is a series of images showing various dams in North America and how they cut off the rivers flow (the might canyons after the dam host only a rivulet). I'm not sure whether this makes me sad to see, or maybe some other emotion that is as yet inarticulate
