On the following day we passed Chimney Rock, visible for a great distance and a striking feature of the landscape. It is about 260 feet in height. Captain Howard Stansbury, an early traveler wrote of it: "This singular formation has been undoubtedly at one time a projecting shoulder of the main chain of bluffs bounding the valley of the Platte and has been separated from it by the action of water. That the shaft has been very much higher than at present is evident from the corresponding formation of the bluff, as well as from the testimony of all our voyagers, for whom it was for years a beacon visible for forty or fifty miles both up and down the river." It was the opinion of Mr. James Bridger that this eminence had been reduced to its present height by lightning or some other energy of nature, from the change he observed in it on his return from one of his trips to St. Louis, for when he had passed it on his way down, it was uninjured. After still another long day's drive up the valley of the swift flowing North Platte, through patches of stunted sage brush and grease wood, we paused for the night. The terraced height of Scott's Bluffs loomed in the distance. Almost behind them, the glowing sun sank beneath the sharply defined horizon, and the shadows of night brought welcome relief after another day of intense heat. CHAPTER XIII The Mystery of Scott's Bluffs As is well known, a wonderful story may be enfolded in the mute testimony of the hills and rocks, and far more enduring than ever written by human hands. Some of these interesting records, open to any observer, are as plainly written in the exposed cliffs of Scott's Bluffs as in any spot that I have known. Their location was noted upon the old maps partly perhaps because they had received a name in memory of the tragic death from starvation of a man who was deserted by his companions on Laramie Fork. Scott was too ill to continue his journey, and the entire party was destitute of provisions. He lived, however, to make his way alone to these Bluffs, where his remains were eventually found. The altitude of the Bluffs as given in the Government survey is 4,662 feet above sea level, a fact in no way remarkable except as fixing the highest elevation attained in Nebraska. The isolated position of this vast pile makes it a conspicuous object when viewed from no matter what direction. It rises abruptly from a comparatively level plain upon which it was once believed no vegetable life could ever grow, for the surface of the surrounding country was as barren and bare as a brick pavement. The rock at once arouses interest by virtue of its beautifully terraced formation, and picturesque outlines embellished with towers and castles, the handiwork of Nature. There it stands, in majestic solitude, guarding its silent chambers, innumerable records of a remote antiquity,--an ancient ruin compared with which the storied monuments in the valley of the Nile are modern and insignificant.
