Minerals are seeping through the cracks on the embankment. Its probably 50 plus years of mineral buildup... like caves I've seen in Colorado... just add a few zeroes!
I photographed the embankment with my Canon 5D camera and 70-200 mm lens.
Thank you @brumest for creating the Monomad Photo Contest!
Thanks for the art @overkillcoin... minnows, dolphins, whales... I’m down with squid!
