Note 115 — {147} CHAPTER VIII {VI}

There is a considerable error in the longitude of points in western Nebraska and Colorado as given on the map of the expedition. For example, the longitude of the town of North Platte, at the confluence of the forks of the Platte, is 100° 45' 53"; while on the accompanying map the one hundred and second meridian runs but little west of the spot. For this reason, and because of the few landmarks described, the location of the camps of the expedition can only be approximated; but that of June 26 must have been quite near the Nebraska-Colorado boundary. The South Platte leaves Colorado almost exactly at the northeastern corner of the state.—Ed.
