Detailed geologic mapping, measured sections, lithofacies analysis, and preliminary paleomagnetic data indicate that sedimentation and deformation in the Mecca Hills resulted from evolution of local fault zone complexities superimposed on regional subsidence and uplift. Sediment was derived from sources northeast of the SAF and transported southeast along the fault zone in large rivers, alluvial fans, and a smaller fault-bounded lake.

    By CORNELIUS COLE SMITH Riverside, California 1 must go now to the places where the sunset Throws shadows on the high red walls of rock. Where starlight falls upon those silent hills. And sun and moon are calendar and clock. I will see the giant cactus spear a passing cloud, And rift its fleecy vapor into shreds. And catch the glint of copper-rock and moonstones From their place in empty river beds. I will walk into some long forgotten town. See lizards run beneath the stones when I draw near. And close my eyes to see a cavalcade of things. Pueblo Bonita Ruins in Chaco Canyon. Photo courtesy Charles S. Webber. That vanished in some ageless bygone year. WESTERN EYES THE DESERT By PHYLLIS W.

    By EVA L. ROBINSON Los Angeles, California It's true that winter's on the wane, For daylight hours are showing gain. If drab and dry the desert lies Beneath the cold and cloudless skies. I do not moan, for this I know— The desert will awake and glow As wave on wave of colors flow— If there is rain. I love the desert's calm repose In garb of gray and mauve and rose— Its tinted dawn—its sunset skies— Its silent mountain peaks that rise Like sentinels to guard the plain. From all that hunger to obtain Possession of the vast domain— If there is rain. We lift our eyes and pray there will Fall blessings from the skies until The dormant life without a sound, Springs up in legions from the ground. Buds will appear mysteriously, To bloom in grace and purity, Where there is none but God to see— If there is rain. • • • UNTOUCHABLE By GRACE BARKER WILSON Kirtland, New Mexico The tawny, untamed desert stretches on In sandy dryness of unnumbered years. No civilizing thing yet interferes As endless time is marked from dawn to dawn. No point of conquering plow yet penetrates The wastes that lie around the stony peaks In desolation. There the redman ekes A meager living as he concentrates His energy upon a flock of sheep That draw scant strength from scattered wisps of grass. Unchanged, unchanging as the decades pass. The frontier stops, and progress is asleep. BRIGAND By VADA F. CARLSON Winslow, Arizona The chaparral cock—droll desert cuckoo!— Mariposa Lily.

  • Sedimentation and Deformation in a Pliocene–Pleistocene Transtensional Supradetachment Basin, Laguna Salada, North-West Mexico R
    Basin Research (1999) 11, 205–221 Sedimentation and deformation in a Pliocene–Pleistocene transtensional supradetachment basin, Laguna Salada, north-west Mexico R. Dorsey* and A. Martı´n-Barajas† Department of Geological Sciences, 1272 University of Oregon, Eugene, OR 97403–1272, USA †Departamento de Geologı´a, Centro de Investigacio´ n Cientı´fica y de Educacio´ n Superior de Ensenada, Baja California, Mexico ABSTRACT This study examines a thick section of Pliocene–Pleistocene sedimentary rocks exposed in the footwall of an active normal fault (Can˜on Rojo fault) near its intersection with the dextral- normal Laguna Salada fault in north-western Mexico. These rocks are situated in the upper plate of an inactive strand of the Can˜ada David detachment fault, which is cut on the north- east by the Laguna Salada fault. The stratigraphy is divided into three unconformity-bounded sequences: (1) marine mudstone of the Pliocene Imperial Formation; (2) nonmarine Pliocene– Pleistocene redbeds, consisting of sedimentary breccia, conglomerate, conglomeratic sandstone (all un-named) and fine-grained sandstone and mudstone of the Palm Spring Formation; and (3) uncemented Pleistocene boulder gravel. Coarse deposits of the redbeds sequence were deposited in fault-bounded, high- and low-gradient alluvial fans that passed laterally into a low-energy fluvial plain of the ancestral Colorado River (Palm Spring Formation) which occupied the present-day Laguna Salada. Detailed mapping reveals convergence and lap-out of bedding surfaces in the redbeds sequence onto the west limb of a large anticline cored by Imperial Formation. These geometries, combined with fanning dips and thickening of stratigraphy into the flanking syncline, indicate that the anticline grew during deposition of the redbeds.
