Summary Authors: Anne Miller; Jim Foster
This photo was snapped while standing behind the top of Ribbon Falls in Grand Canyon National Park, Arizona. Stream water from a tributary of Bright Angel Creek pours from the cap rock above onto a great mound of travertine and moss (bottom of photo). This mound is formed by mineral deposition that occurs as the falling water splashes off rocks along its way to the bottom of the falls. Much of the water evaporates in the very dry air, leaving behind traces of travertine and other minerals. Photo taken on July 13, 2016.
