Desert Landforms and Surface Processes
in the Mojave National Preserve and Vicinity
By Philip Stoffer 1
Open-File Report 2004-1007
2004
ABSTRACT: Landscape features in the Mojave National Preserve
are a product of ongoing processes involving tectonic forces, weathering,
and erosion. Long-term climatic cycles (wet and dry periods) have
left a decipherable record preserved as landform features and sedimentary
deposits. This website provides and introduction to climate-driven
desert processes influencing landscape features including stream
channels, alluvial fans, playas (dry lakebeds), dunes, and mountain
landscapes. Bedrock characteristics, and the geometry of past and
ongoing faulting, fracturing, volcanism, and landscape uplift and
subsidence influence the character of processes happening at the
surface.
