[Illustration: Mt. Hayden, or the Great Teton. This picture represents one of the monarch peaks of the Rocky Mountains. It is visible on a clear day for a radius of one hundred and fifty miles in every direction, thus forming one of the most conspicuous landmarks in the West. It is probable that the only white men that ever reached its summit are Mr. James Stevenson and Hon. N. P. Langford. The elevation is thirteen thousand four hundred feet. It is seen by the traveler on the overland stage-road to Montana, from the Snake River Basin, far to the eastward, rearing its “Bald awful head” far above the limit of perpetual snow.] [Illustration: Panoramic View of the Teton Range. This photo presents a panoramic view of the north portion of the Teton Range. The peaks in the distance are composed of massive granites, while the rocks in the foreground are limestones. For beauty as well as grandeur, no description can convey any adequate idea of it.] [Illustration: Camp at the Mouth of Teton Canyon. This camp is in the Teton Canyon, and West of the Teton Range, just ten miles by Triangulation to the summit of the Grand Teton. The trees are all pines and firs. As the sun rises in the morning immediately back of the peaks, it invests them with remarkable beauty. The scenery along the Teton River is rugged and most attractive. It furnished some of the finest views taken on the Survey.] [Illustration: Crater of the Architectural Geysers, Lower Basins. This picture represents one of the handsomest fountain springs in the Lower Basin. The entire mass of the water is at times most violently agitated, and is thrown up by a succession of impulses forty to sixty feet. The water overflows the borders, producing the wonderful ornamentation which is so clearly shown in the photograph. The peculiar coral-form masses of pearly silica are well brought out. The crater is about twenty-five feet in diameter, and the water when quiet has a temperature of about 180°.] [Illustration: Upper Firehole Basin from the Crater of Old Faithful. Old Faithful derived its name from the regularity of its action, which occurs once in sixty-five minutes. When it is in operation it throws a column of water, by a succession of impulses six feet in diameter, to the height of one-hundred and sixty feet. The paroxysm continues about twelve minutes when the water sinks down in the crater, and all is quiet. The silicious deposits around the crater are marvels of beauty. The Madison River can be seen in the distance and also the geysers in operation.]
