Visiting Yellow Stone National Park with a local guide

December 5th-19th, 2012, a group of high-level Tibetan scholars and business people visited the USA on tour of ecotourism sites and educational institutions.  They started in San Francisco, where they visited several parks, including the Marin Headlands, Mt. Tamalpais, and the Muir Woods National Monument, home of the tallest trees on earth.  They then visited Yellowstone National Park where they saw bison, elk, coyotes, wolves, and more in their natural setting.  Finally, they visited sites in Washington DC, and New York City, including the beautiful campus of Columbia University.
