Note III-5 — Chapter III · ITINERARY, CONCLUDED: IN THE MOUNTAINS OF COLORADO ON HEADWATERS OF THE ARKANSAW AND RIO GRANDE, DECEMBER 1ST, 1806-FEBRUARY 26TH, 1807.

One of these is, of course, the main Arkansaw, in the Royal Gorge; the other, on the left, or S., is Grape cr., which runs through the Wet mts. to its confluence with the Arkansaw a mile or so above Cañon City, under Noonan's Peak. Grape cr. used to be called Pike's fork of the Arkansaw, as by Gregg, 1844; but this name lapsed. Bringing it in for a moment, we find the "forks" of the Arkansaw to be: 1st fork of Pike, Purgatory r.; 2d fork of Pike, Huerfano r.; 3d fork of Pike, St. Charles r.; Grand forks of Pike, confluence of Fountain r. with the Arkansaw; Pike's fork of some books, Grape cr. From his present position at Cañon City, Pike explores the Royal Gorge and Grape cr. to some little extent, and abandons them both; he scouts about for the Spanish trail, and having found it, as he supposes, starts N., up Oil cr., very likely by the present road from the town to that stream.
