The deep wash pinched in, as the other had done, before it gave out into the plain; and, then, as he whirled around a point, he glided out into the open. The foothills lay behind him and, straight athwart his way, stretched a sea of motionless sand-waves. As far north as he could see, the ocean of sand tossed and tumbled, the crests of its rollers crowned with brush and grotesque drift-wood, the gnarled trunks and roots of mesquite trees. To the east and west the high mountains still rose up, black and barren, shutting in the sea of sand; but across the valley a pass led smoothly up to a gap through the wall of the Panamints. It was Emigrant Wash, up which the hardy Mormons had toiled in their western pilgrimage, leaving at Lost Wagons and Salt Creek the bones of whole caravans as a tribute to the power of the desert. A smooth, steep slope led swiftly down to the edge of the Valley of Death and as Wiley looked across he saw as in a vision a massive gateway of stone. It was flung boldly out from the base of a blue mountain, enclosing a dark valley behind; and from between its lofty walls a white river of sand spread out like a flower down the slope. It was the gateway to the Ube-Hebes, just as Charley had described it, and it was only a few miles away. It lay just across the sand-flat, where the great, even waves seemed marching in a phalanx towards the south; and then up a little slope, all painted blue and purple, to the mysterious valley beyond. The sun, swinging low, touched the summits of distant sand-hills with a gleam of golden light and all the dark shadows moved toward him. A breath of air fanned his cheek, and as he drank deep from his canteen he nodded to the Gateway and smiled. CHAPTER XXIX ACROSS DEATH VALLEY The way to the Ube-Hebes lay across a low flat, glistening white with crystals of alkali; and as his car trundled on Wiley came to a strip of sand, piled up in the lee of a prostrate salt bush. Other bushes appeared, and more sand about them, and then a broad, smooth wave. It mounted up from the north, gently scalloped by the wind, and on the south side it broke off like a wall. He drove along below it, glancing up as it grew higher, until at last it cut off his view. All the north was gone, and the Gateway to his hiding-place; but the south and west were there. To the south lay mud flats, powdery dry but packed hard; and the west was a wilderness of sand.
