Having no saddles, they secured buffalo robes on the backs of two mules--Killbuck, of course, riding his own--and lost no time in proceeding on their way. They followed the course of the Indians up the stream, and found that it kept the cañons and gorges of the mountains where the road was better; but it was with no little difficulty that they made their way, the ground being much broken and covered with rocks. Killbuck's wound became very painful, and his leg stiffened and swelled distressingly, but he still pushed on all night, and, at daybreak, recognising their position, he left the Indian trail, and followed a little creek which rose in a mountain chain of moderate elevation, and above which, and to the south, Pike's Peak towered high into the clouds. With great difficulty they crossed this ridge, and ascending and descending several smaller ones which gradually smoothed away as they met the valley, about three hours after sunrise they found themselves in the south-east corner of the Bayou Salade. The Bayou Salade, or Salt Valley, is the most southern of three very extensive valleys, forming a series of table-lands in the very centre of the main chain of the Rocky Mountains, known to the trappers by the name of the "Parks". The numerous streams by which they are watered abound in the valuable fur-bearing beaver, whilst every species of game common to the west is found here in great abundance. The Bayou Salade especially, owing to the salitrose nature of the soil and springs, is the favourite resort of all the larger animals common to the mountains; and, in the sheltered prairies of the Bayou, the buffalo, forsaking the barren and inclement regions of the exposed plains, frequent these upland valleys in the winter months; and feeding upon the rich and nutritious buffalo grass which, on the bare prairies, at that season, is either dry and rotten or entirely exhausted, not only are enabled to sustain life, but retain a great portion of the "condition" that the abundant fall and summer pasture of the lowlands has laid upon their bones. Therefore is this valley sought by the Indians as a wintering ground; and its occupancy has been disputed by most of the mountain tribes, and long and bloody wars have been waged to make good the claims set forth by Yuta, Rapaho, Sioux, and Shians. However, to the first of these it may be said now to belong, since their "big village" has wintered there for many successive years; whilst the Rapahos seldom visit it unless on war expeditions, against the Yutas.
