Assignment Help | On the geology of Yosemite National Park.

Students, On 11 April 2005 my wife and I visited Yosemite National Park, California. I had never been to the park although my wife was there during her parents in the 1950s; she says that Yosemite is spectacular beyond belief.

Thus I have prepared the following DB 9 to deal with the geology of Yosemite National Park. During our visit we explored the geological/environmental/biological features of the park; some of our observations are reported to you, including some slides (PPT) in Course Documents. Hopefully our experiences/explorations will add additional significance to your discussions.
