Pence Landscape
Pence Landscape .This is the rolling landscape of the eastern portion of the San Joaquin valley, California where the alluvial parent material that fills the valley and the rocks that form the foothills of the Sierra Nevada are found intermixed. The high area in the distance is a bedrock high, parent material for the Pence soil. In between the higher portion of the landscape and the photographer is alluvium. The bedrock parent material of the Pence series is volcanic rock that consists of minerals rich in plant nutrients. The grasses that grow on the soil formed on this type of parent material yield more than those that grow on other volcanic rocks in the area. In addition, they have higher nutrient value for the cattle that graze here.
