Analysis of treeline annual growth at a site in the southern SierraNevada, California, indicates that much of the past climate variability on timescales of centuries to millenia during the Holocene may be attributed to periodic changes in solar
irradiance. Analysis of treeline-altitude variation in the SierraNevada and White Mountains of California suggests that this periodic change is superimposed on a generally decreasing temperature trend over the past 5000 years. This has led to a general
It is hypothesized that the White Mountains have a similar glacial chronology to the adjacent SierraNevada, but that with the intensification of the Sierran rainshadow during the Quaternary, the extent of glaciation in the White Mountains
apparently decreased through time owing to regional tectonic uplift. This had led to the preservation of a more complete sequence of glacial deposits than in the SierraNevada.
Utilisation de la dendroclimatologie en liaison avec la datation lichénométrique de dépôts glaciaires pour interpréter les conditions climatiques et glaciaires de l'Holocène et ajuster la chronologie de ces événements à la SierraNevada Sud.

Perimeter shape of drainage basins is evaluated as a control of annual runoff depth from small SierraNevada basins underlain by granitic rocks. In contrast to three perimeter shape ratios, none of which contributes a statistical explanation

Author challenges the common wisdom that the world's great ranges, including the SierraNevada, experienced major uplift in late-Cenozoic time. Three independent methods (longitudinal profiles of canyon-bottom flows and deposits, weathering rates
Uplift and erosion creates truncated spurs on fault-controlled mountain slopes. The stepped morphology of these spurs reflects the uplift history of the SierraNevada since late Serravallian times. Digital Elevation Models (DEMs) offer a method
