MOUSE VISITS YOSEMITE NATIONAL PARK Mouse watches snow melting around his home and decides that Yosemite National Park with all its waterfalls must really be running so this is where he needs to visit next. What he isn't prepared for is how many huge waterfalls there are in Yosemite or how many huge rocks there are in Yosemite-and that people like to climb them. Mouse is in for excitement on this trip. Come along with Mouse and see the beauty and reason for our National Parks.
