John M. (John Maxwell) Good

John M. Good, sometimes listed as John Maxwell Good, wrote about geology and natural history in a way that welcomed non-specialists in. He is credited as an author of The Dinosaur Quarry: Dinosaur National Monument, Colorado-Utah, and he later co-authored Interpreting the Landscapes of Grand Teton and Yellowstone National Parks with geologist Kenneth L. Pierce.

Reliable sources also connect him to a long career with the U.S. National Park Service. According to the Coalition to Protect America's National Parks, he began as a tour leader at Carlsbad Caverns National Park, later worked as a naturalist at Lake Mead, Dinosaur National Monument, and Yellowstone, and served for a time in Washington, D.C., as the Park Service's chief geologist.

That background helps explain the tone of his books: they are grounded in field experience and written to help ordinary visitors understand what they are seeing. For readers and listeners interested in dinosaurs, rocks, and the story of how western landscapes were formed, his work offers an accessible guide from someone who knew the parks from the inside.
