The photographs here are by James L. Reveal and by A. Scott Earle.

In the spring of 2003, a book by Earle and Reveal entitled Lewis and Clark's Green World: The Expedition and its Plants was published by Farcountry Press. A CD by Earle E. Spamer and Richard M. McCourt, entitled Lewis and Clark Herbarium (CD) and also published in 2003, is available from the Academy of Natural Sciences.
