Note 51 — MEMORANDOM OF THE VOIGE BY LAND FROM FORT SMITH TO THE ROCKEY MOUNTAINS.

A statement which serves to fix camp with perfect precision. The two mounds said are both between one and two miles due W. of Caddoa, and just the distance said W. of Caddoa creek. These isolated elevations appear in due form on the U. S. Geological Survey map of Colorado, Lamar sheet, near lower left-hand corner. The railroad cuts between the river and these bluffs, but the wagon road rises over them, back of their tops. See Pike, ed. of 1895, p. 443.
