Investigations into processes of ventifact formation in the east-central Mojave Desert confirm the importance of topography as a control in the location, orientation, and intensity of ventifact abrasion.
Soil genesis on beach ridges of pluvial lake Mojave : implications for Holocene lacustrine and eolian events in the Mojave Desert, Southern California
Silver Lake and Soda Lake playas, Mojave Desert, California, are bounded by locally well preserved shoreline, features that reflect the presence of pluvial Lake Mojave. Morphological, textural and chemical analysis of the soils indicate that eolian
Aeolian destabilization along the Mojave River, Mojave Desert, California : linkages among fluvial, groundwater, and aeolian systems

This paper demonstrates how changes to the aeolian environment of the Lower Mojave Valley in recent decades represent complex interactions between the wind regime, river channel morphology and sediment, surface hydrology, subsurface hydrology
Short-duration Holocene lakes in the Mojave river drainage basin, southern California
Discusses evidence of middle to late Holocene lake-level fluctuations recorded in the terminal basins of the Mojave River. Presents stratigraphic and sedimentologic evidence of the occurrence of shallow, short-duration, middle to late Holocene lakes
in the terminal playas of the Mojave River in southern California. A possible cause for these short-term wet climatic episodes, as recorded by historic and Holocene lakes is proposed.
Cation ratio dating of quaternary materials in the east-central Mojave Desert, California

Mise en évidence d'une bonne corrélation entre les méthodes de datation du Quaternaire K-Ar, radiocarbone et de l'étude des rapports des cations K + Ca : Ti dans les vernis désertiques du Désert Mojave, Californie.
It appears that in the sparsely vegetated Mojave Desert, the C13/C12 of pedogenic carbonate is controlled by differences in plant density and biological activity. This relationship may provide a tool for assessing past vegetational densities
Analyse sur seize ans du mouvement de pierres peintes sur deux versants du désert Mojave central afin de déterminer le processus prépondérant du transport des débris grossiers, creep ou action hydraulique. Le fait que la distance parcourue soit plus
étroitement corrélée avec la longueur de l'écoulement superficiel qu'avec l'angle de la pente suggère la prédominance de l'action hydraulique. Ceci est probablement le cas pour la plupart des déserts Mojave et Sonoran sur les pentes jusqu'à 24 au moins. C'est
Use of multiparameter relative-age methods for age estimation and correlation of alluvial fan surfaces on a desert piedmont, eastern Mojave Desert, California
Lake Manly(?) shorelines in the Eastern Mojave Desert, California
shorelines were probably formed by the Blackwelder stand and subsequently displaced , tectonically, due to transpression in the northeastern Mojave Desert and NW-SE extension across Death Valley. This tectonic regime would result in subsidence of Death Valley
Elevational shifts of Coleogyne ramossissima in the Mojjave Desert during the Little Ice Age
In this paper, the AA. add to the knowledge of vegetation changes in the Mojave desert during the Little Ice Age through study of fossil woodrat middens located in the eastern part of the desert where substantially greater amounts of precipitation
Geomorphology and sediments of sand ramps in the Mojave Desert
Sand ramps are amalgamated accumulations of aeolian, fluvial, and talus deposits. They have developed as a result of the interaction of wind blown-sand and desert piedmont processes adjacent to mountain ranges in the Mojave Desert and occur next
to regional and local sand transport corridors. Periods of geomorphic stability are represented by paleosols and talus accumulations. The sand ramps provide a record of the response of aeolian processes to climatic change in the Mojave Desert. Most are now
Luminescence dating of sand ramps in the Eastern Mojave Desert
+The results of a luminescence dating program involving 78 samples of material from 9 sand ramp complexes have enabled recognition of regional and local patterns of sand accumulation in the Eastern Mojave Desert. The study area extends from Lake
as a critical condition for accumulation of material on the sand ramps during the Late Quaternary in the Eastern Mojave.
The AA. examined 27 reservoirs in the northern and eastern Mojave Desert that trapped sediment from small drainage basins on alluvial fans over the past 100 yr, calculated annual sediment yield, and estimated the average recurrence interval (RI
Late Holocene vegetation changes in Greenwater Valley, Mojave Desert, California

Small-scale late Holocene vegetation changes were determined from a series of 13 modern and fossil packrat middens collected from a site in the Greenwater Valley, northern Mojave Desert, California. Although the site is above the modern lower limit
Response of alluvial fan systems to the late Pleistocene to Holocene climatic transition : contrasts between the margins of pluvial lakes Lahontan and Mojave, Nevada and California, USA
to the early Holocene, may be due to climatic, vegetation, or other differences between the fan environments. During the late Pleistocene, both fan systems terminated in pluvial lakes, Lake Lahontan in Nevada and Lake Mojave in California. In both cases, dated
Temporal and spatial aspects of blowing dust in the Mojave and Colorado deserts of southern California, 1973-1994
Dust events in the Mojave Desert characteristically occur during the winter to spring months (February-May), associated with dry frontal activity, and are largely absent during the dry summer months. The Colorado Desert experiences a similar
