Mark Behan (1931–2008) was a professor of botany at the University of Montana, where he taught courses in plant physiology, ecology, identification, and the uses of plants by mankind. He spent several year-long assignments in Nepal and Pakistan working on university and faculty development. His ten-year affiliation with the Bombay Natural History Society focused on endangered fauna of Indian grasslands, and invasive plants of protected areas in India.
Contributions
As a reference, Lewis purchased the second edition (1784) of Richard Kirwan’s Elements of Mineralogy. Although Lewis and Clark had the book at hand throughout the expedition, its usefulness as a field guide was limited.
The expedition camped amid very picturesque boulders of pink granite at Lolo Hot Springs, and crossed large masses of it on their way across Idaho.
