Abstract

The current configuration of Nevada’s landscape has changed more than one could imagine. Early in the evolution of the Basin and Range, the currently extended landscape was once a massive “plano”, which refers to a large flattened plateau with elevations on par with a mountain range. Since the late Cenozoic, Nevada has been known for large basins and hill sloped ranges; none of which would be consider in the same realm of height and magnitude as the Nevadaplano. Through studies of modern day analogs, such as the South American Altiplano, we can draw similarities to the shape and magnitude of the Nevadaplano. These studies show that the South American Altiplano has similar shape, magnitude, and underlying plate movement compared to the Nevadaplano. Sedimentary rocks provide evidence for understanding the elevation gains and the origin of the Nevadaplano in western North America during the Cenozoic. Methods comparing the rate of sedimentary deposition and erosion help to correlate the rising of the region east of the Rockies into the Nevadaplano. Similarly, C-14 and O-18 studies of fossil plants from the region have correlated high altitude conditions of the region.
