Spring Mountain District AVA - Soils


Soil depths vary, but tend to be deeper than in nearby mountain terrain and shallower than on the valley floor. The region contains mostly residual upland soils with only a few areas of alluvial soils at the lower elevations. The soils are derived almost equally from Franciscan sedimentary rocks (sandstone and conglomerates) and Sonoma volcanic formations which are predominately composed of Andesite. This equal mix of sedimentary and volcanic rocky soils distinguishes the region from adjacent mountain areas. To the north, in the Diamond Mountain area, soils are almost entirely of volcanic origin. To the south, in the Mount Veeder area, soils are primarily sedimentary.

Famous quotes containing the word soils:

    He bends to the order of the seasons, the weather, the soils and crops, as the sails of a ship bend to the wind. He represents continuous hard labor, year in, year out, and small gains. He is a slow person, timed to Nature, and not to city watches. He takes the pace of seasons, plants and chemistry. Nature never hurries: atom by atom, little by little, she achieves her work.
    Ralph Waldo Emerson (1803–1882)
