"The bighorn (carnero cimarron, as called by the Mexicans, and sometimes known to trappers as the mountain sheep), so abundant in most of the Rocky Mountain chain, is found in the spurs and table-plain cliffs about the sources of the Cimarron river (whence this stream acquired its name), as well as in the highland gorges, and other parts of those mountain borders. Its flesh is said to be excellent, and is preferred by many hunters to venison. ...It is most remarkable for its huge spiral horns, resembling in shape and curvature those of the sheep, but sometimes over three feet long, and four to six inches in diameter at the base. The bighorn is quite celebrated for its agility, and its habit of secluding itself among the most inaccessible mountain crags. It seems to delight in perching and capering upon the very verge of the most frightful precipices and overhanging cliffs, and in skipping from rock to rock, regardless of the yawning chasms, hundreds of feet in depth, which intervene. In fact, when pursued, it does not hesitate, as I have been assured, to leap from a cliff into a valley a hundred or more feet below, where, lighting upon its huge horns, it springs to its feet uninjured; for the neck is so thick and strong as to support the greatest shock the animal's weight can bring upon it. Being exceedingly timorous, it rarely descends to the valleys, but feeds and sleeps about such craggy fastnesses as are inaccessible to the wolves and other animals of prey. This animal seems greatly to resemble the moufflon of Buffon, in color, figure and horns, but the chamois in habits."
