Tuesday, GeoJourney visited Yosemite National Park, CA where we were awed by the immense amount of water freshly melted from the top of the High Sierras.  Bridalveil, Yosemite, Vernal, and Nevada Falls could be heard roaring from our view at Glacier Point.  Students learned about the numerous glacial features that could be seen from the spectacular overlook above the U-shaped valley of the national park.

We also paid visit to Tuolumne Grove, where some of the largest trees on the planet grow: giant sequoias. These trees can vary in height from 290 to 360 feet tall and contain about 50,500 cubic feet of wood the equivalent volume of 21,800  people!  Being able to walk through a dead, hollowed out sequoia, gave us a chance to put these numbers into perspective.  Later, a hike up the Mist Trail to the top of Vernal Falls gave us a chance to cool off in the snow-chilled waterfall mist. We now have made our way into Marin County, where we will stay while visiting the San Francisco area. Tomorrow is our geohazard day in San Francisco…so stay connected to find out about our experience learning about earthquakes.
