Soda Lake, normally a dry lake bed, is one of the dominant geographic features of the Carrizo Plain. It is the largest remaining natural alkali wetland in southern California and the only closed basin within the coastal mountains. As its name suggests, Soda Lake concentrates salts as water evaporates, leaving white deposits of sulfates and carbonates that look like baking soda.
This remote monument, traversed by the San Andreas Fault which has carved valleys, created and moved mountains, and yet up close, is seen in subtle alignment of ridges, ravines and normally dry ponds. Prominent features on the monument include the white alkali flats of Soda Lake, Painted Rock, vast open grasslands, and a broad plain rimmed by mountains. When conditions are right, numerous wildflowers can carpet the valley floor; although short lived it can be breathtaking.
