by bad-land hills, dominated with the towering cliffs of Tavaputs, the
bold escarpment of the Wasatch Plateau, and the volcanic peaks of the Henry Mountains on the south. It is a vast forest of rock forms, and in its midst is San Rafael Swell, an elevation crowned with still more gigantic rock forms. Among the rocks pools and lakelets are found, and little streams run in canyons that seem like chasms cleft to nadir hell. San Rafael River and Fremont River drain this Castle land, heading in the Wasatch Plateau and flowing into the Grand River. Along these streams a few narrow canyon valleys are found, and in them Ute Indians make their winter homes. The bad lands are filled with agates, jaspers, and carnelians, which are gathered by the Indians and fashioned into arrowheads and knives; along the foot of the canyon cliffs workshops can be discovered that have been occupied by generations from a time in the long past, and the chips of these workshops pave the valleys. South of the Wasatch Plateau we have the Fish Lake Plateau, the Awapa Plateau, and the Aquarius Plateau, which separate the waters flowing into the Great Basin from the waters of the Colorado, which here constitute the boundary of the Plateau Province. Awapa is a Ute name signifying "Many waters." All three of these plateaus are remarkable for the many lakelets found on them. To the east are the Henry Mountains, a group of volcanic domes that rise above the region. The rocks of the country are limestones, sandstones, and shales, originally lying in horizontal altitudes; but volcanic forces were generated under them and lavas boiled up. These lavas did not, however, come to the surface, but as they rose they lifted the sandstones, shales, and limestones, to a thickness of 2,000 or 3,000 feet or more, into great domes. Then the molten lavas cooled in great lenses of mountain magnitude, with the sedimentary rocks domed above them. Then the clouds gathered over these domes and wept, and |
