Grasshoppers, and even butterflies, as we have seen, are occasionally subjected to the same treatment, with the same result. By-and-by, when the geyser regions become a popular resort, the preparation of petrifactions to be carried away as mementos, may become quite an item of entertainment if not of industry. To obtain a complete view of the Lower Geyser Basin, Colonel Barlow made a trip to the summit of the Twin Buttes on the west side of the basin. From this point the valley of Firehole River could be overlooked for a distance of twenty miles; but nothing new was discovered except an attractive fall plunging over a precipice a short distance to the south. After much severe climbing over rocky ridges, and scrambling through deep and thickly wooded ravines, he succeeded in reaching the foot of the fall--the loveliest vision he had ever beheld. "Towering above my head," he writes, "was a perpendicular cliff, three hundred feet high, while from a slight depression in its upper edge descended a sparkling stream, dashed into spray as it impinged against projecting angles of the rocky wall. On reaching the bottom the mist is gathered into a shallow basin, forming a pool of clear cold water, delightfully refreshing in this region of steaming geysers and volcanic heat. After resting a moment in this quiet retreat, the water slowly finds its way through the forest, and crossing the geyser valley eventually reaches Firehole River, some two miles distant." From the marshy ground about the fall the pines shoot upward to an astonishing altitude, as though ambitious to overtop the cliff. Colonel Barlow approached the fall through a natural avenue in these pines, and as he caught sight of its dancing water, leaping with life-like action down the face of the overhanging cliff, the thought of fairies was so strongly suggested that he could think of no name so appropriate as the Fall of the Fairies.
