In the late 19th and early 20th centuries, photographers traveled to Yellowstone to capture images of the region's geological wonders. Today, many photographers, such as Sean Campbell, document the wildlife living in and around the park. Why do you think people today have more of an interest in the wildlife of Yellowstone? What might have caused this change in interests?
