Note III-7 — Chapter III · ITINERARY, CONCLUDED: IN THE MOUNTAINS OF COLORADO ON HEADWATERS OF THE ARKANSAW AND RIO GRANDE, DECEMBER 1ST, 1806-FEBRUARY 26TH, 1807.

Pike has gone N. from Cañon City some 30 or 35 m., having Oil cr. on his right, and having crossed certain of its tributaries from the west known as Wilson, South Oil, and High creeks. He is now camped on West Oil cr. (the western one of the two main branches), at or near a place called Truro. This is a sufficiently well known locality, in a nest of mountains whence Oil cr. gathers several affluents from various directions. On another branch of the creek is the place called Alnwick, near where Riggs used to have his ranch, or in the same place. West Oil cr. is also called Ten Mile cr.; another small stream is Martin's or Slate cr. Some of the surrounding points are: Mt. Pisgah, 10,322 or 10,487 feet high; Rhyolite Peak, 10,860; Dome Rock or the Needle, 9,463 feet—these on Pike's right as he faces N., and S. W. to W. of his peak; while on his left are in succession: Iron Knoll or Trachyte Knob (lettered "Trackite" on G. L. O. map, 1892); Saddle mt.; Thirty-nine Mile mt., 11,000 feet; Chalcedony Buttes, 10,400 and 10,200 feet. Now the usual way out of this place is N. by Alnwick or Rigg's ranch, between Dome Rock and Saddle mt., over a divide about 9,200 feet high, known as Two Creek or Twin Creek Pass, which fetches out on S. Platte waters at Florissant, on the W. border of El Paso Co.; but Pike takes a route to the left, up West Oil or Ten Mile cr.
