While short and sweet, it's a pity this little pamphlet is not more widely available, especially to students, writers, and researchers of anything involving L&C.;This fantastic little booklet reprints the letter that the Captains had left on the coast, and the eventual amazing history of one copy of it! Maybe they weren't 100% sure they'd ever make the trip back?! This is the kind of wonderful "nugget trivia" that had passed by me in reading the Journal itself.This little pamphlet is focused, of course, on the stay at the coast. Excellent maps are shown, both original and modern. I had not realized, nor ever heard before, what the historical society had actually found in that area, and when. Totally fascinating!This is the ONLY source I've ever seen that gives the names of numerous rivers and other features, as L&C; named them, as the Indians named them, and as they are currently named today!Highly recommended and very, very valuable!
