This suggests that the coupling between soil production and denudation in granitic landscapes harbors a crucial tipping point; if soils are stripped to bedrock, erosion slows and soil formation is restrained to the point that bare rock can persist and rise in relief relative to surrounding soil-mantled terrain.

Contrary to one of the main underpinnings of Wahrhaftig’s hypothesis, our observations suggest that the presence or absence of soil cannot be predicted from hillslope gradients alone.

Nevada's highest point is Boundary Peak, 13,140 ft (4,007 m), in the southwest.

Nevada has a number of large lakes and several large saline marshes known as sinks.

California’s Eastern Sierra Nevada boasts more than a dozen 14,000-foot peaks, some of the longest lines in the country from high alpine to sagebrush, and a ski history dating to the 1800s.

Yet, very few skiers ply its slopes when winter brings a deep, often stable snowpack. We’ve got store-bought firewood, ropes, ice axes and crampons, a pair of two-burner Colemans, and furnishings enough for a first-class safari base camp.

This beautiful and detailed, full-color map covers the Sierra Nevada Range from Lassen National Park in the north to Tehachapi Pass in the south.

The canyon carved by the mighty Colorado, the river that forms the extreme southeastern boundary of the state, is the site of Nevada's lowest elevation, 479 ft (146 m).

Instead, we observe a mix-and-match of soil and bare rock on gently sloped treads and steeply sloped steps.

This raises the possibility that exposure of bedrock arises from contrasts in material properties rather than from random erosional exposure, as suggested by the hypothesis.
