Grand Canyon by Jason Chin*

I love Mr. Chin's habitat books.  In each book he features a young person with a vivid imagination.
In this book a young girl and a male adult hike the Grand Canyon, seeing the different levels and the wildlife in each ecosystem.
Beautiful illustrations.
Mr. Chin promotes evolution and an old world view (billions of years old) so it provides a great opportunity to discuss the different viewpoints on evolution/creation and how old the world is.
*Highly recommend.
