Discover Great National Parks: Yosemite is an excellent non-fiction book for young learners. It features information of what Yosemite was like before it was a park, how it became a national park, and most of all, the Grizzly Giant, a 30-story tall and thousands of years old Sequoia tree, along with the wildlife that lives there, including the endangered bighorn sheep. Famous visitors to Yosemite are John Muir and President Theodore Roosevelt. See beautiful photographs, both current and historical, of the land, fun facts about the park and learn more through the chapter notes, suggested readings, and glossary.
