Geological history of Point Lobos than it is now (because more water was in the polar ice-caps and continental glaciers). Deep submarine canyons were cut in the Monterey Bay area, as an extension of the Salinas River. During late Cenozoic Era, because of sustained transpression of the Pacific Plate onto the American Plate along the nearby San Andreas Fault Zone, there was continued uplift of the entire coastline of California, so that erosive action of marine waves cut these terraces in the Monterey Bay area. Those Pleistocene marine terraces are composed of clay, silt, sand and gravel with a basal unconformity of gravel on top
Natchez silt loam the bluff hills that border the Mississippi Delta floodplains. They formed in silty loess material that ranges from strongly acid to neutral in the upper part and neutral to slightly alkaline in lower parts. Average annual precipitation is 52 inches. Average annual air temperature is 63 °F (17 °C). The soil has developed in the upper Pleistocene age material. Natchez silt loam In 1988, the Professional Soil Classifiers Association of Mississippi selected Natchez silt loam soil to represent the soil resources of the State. These soils exist on 171,559 acres (0.56% of state) of landscape in Mississippi. The Natchez Silt
