I'd sure like to learn more about Fremont's route(s) from Lassen's ranch to Klamath Lake and back in 1846. For some reason I think they returned a different way than they left--that is, one way via Cow Creek and return via Hat Creek and north fork of Battle Creek. From my notes on that I can't tell whether this notion comes from Ruby Johnson Swartzlow's, "Lassen, his life and legacy" (Mineral, California: Loomis Museum Association, Lassen Volcanic National Park, 1964), p. 23, or William N. Davis, "Sagebrush Country" (New York: Garland, 1974), p. 35. If they indeed went and returned on different routes, there were two routes we can actually place Lassen on before his 1848 opening of "his" trail.
