TitleJointed and weathered granite outcrop, Sierra Nevada Mountains, California
DescriptionThe granite of the Sierra Nevada Batholith is exposed to harsh alpine conditions and so sharp corners rapidly become rounded. Weathering is aided by the many sets of joints and other fractures that are present and allow water and ice to penetrate the rock.
