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.
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.
