| Image Description: |
Joshua Tree National Park is one of California’s rounded boulder wonderlands, as the multitude of smooth boulders here can attest to. Just after sunrise, warm golden light illuminates a smooth slope of granite with large boulders. A larger collection awaits the afternoon sun behind, and rain attempts to fall from clouds beyond before colliding with turbulent winds and evaporating into virga. The curiously round shapes of the granite here are caused by spheroidal weathering. Acidic water over the centuries seeps into the outer layers of the rock and chemically turns the feldspar crystals in the granite into clay. This facilities the rock fracturing and breaking apart. Since the chemicals can seep deeper into pointed areas rather than the flat parts of a given rock, the pointed bits were progressively eroded until only smooth surfaces remain. Exposure to surface erosion removes all the fractured pieces leaving behind just the smooth and delightful shapes. |
