Shown above is a tufa formation at the now-dry Winnemucca Lake, near Marble Bluff, Nevada. The coral-like tufa is a carbonate precipitate built-up around springs that once emerged into the depths of Pleistocene Lake Lahontan -- a large endorheic body of water that once covered much of northwestern Nevada. For scale purposes, see the dugout and framed door in the lower-right corner of the photo. Photo taken on June 10, 2016.
