A 48‰ decrease in the isotopic composition of hydrated glass from ignimbrites located near paleo-sea level to ignimbrites 100 km to the east reflects the effect of ancient high topography on precipitation. These data show that 31–28 Ma ago, the northern Sierra Nevada had a steep western gradient and elevations similar to the present. This study, placed in the context of other paleoaltimetry studies, suggests that the range was a high topographic feature throughout the Cenozoic and that the majority of uplift occurred in the Late Cretaceous to early Cenozoic, much earlier than some studies have proposed.
