(1.) Many national parks are home to unique geological formations. One example of this would be the geysers at Yellowstone National Park. Can you think of another example?
(2.) The book talks about people across the country who are working hard to protect our national parks, and to expand environmental rights in the United States. Can you name one of these people? What makes their story so special?
(3.) No matter which national park you visit, you're bound to encounter an unusual animal or plant species you can't find anywhere else. Talk about a new species you discovered while reading the book!
