SCHNEIDER The problems of geoarchaeology addressed in this paper were probably most clearly stated very early in the research, almost 40 years ago (Warren and DeCosta 1964). To adequately date the artifact assemblages from the 24 "surface sites" on the high beach lines of Pluvial Lake Mojave, two tasks must be successfully completed: (1) construct the geomorphic history of Lake Mojave from the strafigraphy, topographic re/afionships, radiocarbon dates, and any other useful data, and (2) demonstrate the stratigraphic relationship between prehistoric artifacts and lacustrine deposits of Lake Mojave. These two tasks are addressed in this paper, demonstrating the sequence of beach-ridge INTRODUCTION formation at Lake Mojave (Antevs 1937; Ore and Warren 1971; Wells et al. 1989). Additional data The Mojave River periodically flowed into from other locations within the range of elevations Death Valley during the late Pleistocene and early of the high beach ridges are integrated with Holocene.

  • Quagga Mussels Threaten Western U.S. Waters, Researcher Reports 1 July 2008
    Quagga mussels threaten western U.S. waters, researcher reports 1 July 2008 and are out-competing zebra mussels, O'Neill told the House committee. Last year, quaggas were discovered for the first time in the West in Nevada's Lake Mead and have since been found down the Colorado River in Lake Mojave, Lake Havasu and in various locations in California. "[The spread west] is not a surprise," said O'Neill. "It's something that's been expected to happen."

  • Is There Any Evidence of Mega-Lake Manly in the Eastern Mojave Desert During Oxygen Isotope Stage 5E/6?
    Quaternary Research 57, 177–179 (2002) doi:10.1006/qres.2001.2299, available online at http://www.idealibrary.com on REPLY Is There Any Evidence of Mega-Lake Manly in the Eastern Mojave Desert during Oxygen Isotope Stage 5e/6? I am pleased to have the opportunity to defend and clarify the implication that Ku’s dates are more reliable than those of my hypothesis regarding the extent of the Blackwelder stand of Hooke and Lively (see Hooke and Dorn, 1992) is debatable, Lake Manly during marine oxygen isotope stage 6 (OS6). Let given that both use the -counting technique and thus may suffer me start by addressing a couple of general points. from problems with U migration. First, with reference to the pejorative prefix “mega” in Enzel Salt Spring Hills shoreline. Enzel et al. maintain that this et al.’s comment, let me put the size of the lake under discussion shoreline is cut into colluvium and, at its southeastern end, into in perspective. If water were to fill Death Valley to the 90-m alluvial fan deposits. I agree with the former. On the other hand, level today, the surface area would be 1600 km2 (Meek, 1997), air photos, a map in Anderson and Wells (1997), and my own whereas the area Hale proposed, based on overflow at Ash Hill observations do not support the interpretation that it is cut into an pass, would have been 8000 km2 (Hale, 1985). The surface alluvial fan at its southeastern end. Even if further study shows area of the OS6 lake proposed in my paper is 2800 km2, less that it is, however, Enzel et al.’s statements about the age of than half the size of Hale’s lake and less than twice the size a the fan unit are misleading (1) because they are based on dates 90-m lake would have were it to occupy the valley today.

Since then, archaeologists have cited Rogers' publication and repeated his claim that such a pueblo was located in the Western Mojave Desert. The purpose of this thesis started out as a review of the existing evidence and to locate this pueblo.

A study area was selected to the northeastward of the Nevado Coropuna, the volcano currently covered by the largest tropical glacier on Earth. The current glacier extent, the moraines deposited in the past and paleoglaciers at their maximum extension have been mapped. The present and past Equilibrium Line Altitudes (ELA and paleoELA) have been reconstructed and the chlorine-36 ages have been calculated, for preliminary absolute dating of glacial and volcanic processes.

  • Changes in the Water Budget of the Mojave and the Drying out of the Southwest: New Constraints from the Study of Ancient Deposits
    Changes in the water budget of the Mojave and the drying out of the Southwest: New constraints from the study of ancient deposits John Mering, UCLA Department of Earth and Space Science During the next several centuries, anthropogenic global warming is expected to result in aridification in mid- latitude desert regions such as the Southwestern United States, further reducing hydrologic budgets (Wetherald and Manabe, 2002). In the Mojave region of Eastern California this is problematic, where surface and groundwater resources are already overdrawn to sustain population centers and agriculture. In order to accurately model potential aridification in the Mojave, a thorough understanding of regional climate history is essential. Specifically data on past variability in temperature and hydrology can be used to study regional climate processes and assess the accuracy of computer models. I propose to apply new geochemical methods to deposits from sites in the Mojave in order to study the regional climate history and establish the magnitude of change in summertime temperature, and in the source(s) of moisture in the region, to changing greenhouse gas forcing. Data from paleolakes (Fig. 1) have been used to develop climate reconstructions for the Pleistocene, including the Last Glacial Maximum (LGM) interval, 23,000 to 19,000 years before present (Lyle et al., 2012). Many workers have hypothesized a southward shift of the Polar Jet Stream during this time as major sources for precipitation feeding lakes in eastern and southern California at that time, with aridification being driven by the jet shifting northwards and a resultant decrease in winter storms (Oviatt, 1999; Reheis et al., 2012).
