After all the rain we had earlier this week, the Amethyst Brook waterfall in Pelham was running about as good as it gets. Swirls are not a big thing with me, but I know folks enjoy them so when there is an opportunity I go with the flow.
The swirl texture is a little odd because rather than foam this was mostly bubbles which were bobbing as they moved.
15 sec at f/22, ISO 50. I had to lengthen the exposure time because faster caused the lines to not be continuous.
