| FIELD TRIP: Board the motor coach for our field trip to Yosemite National Park. For tens of thousands of years, humans have changed, and have been changed by, this place we now call Yosemite. “It is by far the grandest of all the special temples of Nature I was ever permitted to enter,” said famed naturalist John Muir. Designated a World Heritage Site in 1984, Yosemite is known for its granite cliffs, waterfalls, clear streams, giant sequoia groves and biological diversity. Two wild and scenic rivers, the Tuolumne and Merced rivers, begin in the park and flow west to the Central Valley. Yosemite is one of the first wilderness parks in the United States and encompasses nearly 1200 square miles. |
