Lower falls of the Grand Canyon of the Yellowstone

Words cannot describe this majestic feature.  The Yellowstone river flows over the resistant rhyolites into a glaciated valley formed by the 'yellow' namesake hydrothermally altered rhyolites.  Volcanic rhyolites cover most of the park.  The girls were so excited to spend their first night in an active volcano at Lake Yellowstone.  The hydrothermal features make this like another planet.
