"The Crossing of the Sierra Nevada in the Winter of 1843-44"

[mokelumnekid]

(this should also be on the history forum I think) By J. C. Fremont, edited by Bob Graham. This is a fascinating account of this crossing and the editor's attempts to trace the route exactly and to identify the location- successfully it seems- of the so called "long camp' where they spent considerable time preparing for the final ascent in the vicinity of Carson Pass.

Scroll down to see info about the book. There is related info by the editor, where one can find links to his research on Fremont's "lost" cannon as well as a crossing of Donnor Pass in 1845.
