LAS VEGAS OF NEVADA "The Meadows" of southern Nevada constitute a vast even plain bor- dered by lofty mountains. Eastward from the town of Las Vegas ex- tends a long arm of these plains, which, as it passes between two ranges and joins Meadow valley to the east, is 6 to 8 miles wide. In this arm of the plain the geologic structure is well displayed (figure 3). w /. Figure 3.—Geologic Cross-section of the Vegas Range, Nevada The attitude of the rocks and the relations of the beveled rock-floor to the overlying wash deposits are more clearly shown than immediately to the east or to the west. Still farther to the eastward, in Meadow valley, where there is a perennial stream occupying its middle, a narrow and deep canyon lias been cut in the old bolson. Tertiary deposits are in-.
