Tumbling - WC #434

I think I may have posted this one before in 2008 - but with the title I chose, I figured I had to post it again for this week's WC.

This is a small part of Great Falls NP down river from the main falls. I took it from high up across the gorge at a long focal length, so the compression really shows. I liked the stacked feel and movement. I intended this to be B&W, but this is also a slight split tone, which I decided I liked better.

Thanks for looking!
