single cliff of greenstone, marked by the slaty limestone that once incased it, rears itself from a crumbled base of sandstones, like the boldly chiseled rampart of an ancient city. At its northern extremity, on the brink of a deep ravine which has worn its way among the ruins, there stands a solitary column or minaret tower, as sharply finished as if it had been cast for the Place Vendôme. Yet the length of the shaft alone is four hundred and eighty feet, and it rises on a plinth or pedestal itself two hundred and eighty."
In some of the canons of the Great Walled River, the Colorado of the West, turrets, pinnacles, and even natural arches stud the
walls with countless imitations of architectural forms, every bend of the stream offering some fresh novelty. In parts of Marble Cañon the high walls are eroded into endless alcoves, caves, towers, weather-beaten castles, and a thousand and one weird or fantastic forms. One night, just below our camp, was a perfect semblance of a ruined castle. Around the indentations which answered for crumbling windows clung carelessly bunches of mosses and ferns, while at one side from a mass of emerald verdure, rendered greener and sweeter by contrast with the miles on miles of barren red cliff up and down, gushed forth a clear spring whose waters, churned to silver, dashed through the vines into the deep river a hundred feet below.

The beetling wall which it surmounted was named "Log Cabin Cliff."
Another class of resemblances are those called "domes." The Domes of the Yosemite are a well-known example, but the Five Domes of the Virgin River in southern Utah are perhaps quite as
