San Joaquin Profile
San Joaquin Profile	The San Joaquin has been nominated as the state soil. It is not the best soil for agriculture or urban uses in California, but it is extensive and interesting. The profile consists of a thin A horizon overlying a clay rich Bt horizon that sits on top of a silica cemented duripan. The hammer is sitting on the ledge formed by the silica cemented horizon. This soil is a Durixeralf. Below the duripan, the mostly unweathered gravelly alluvium is the parent material for the soil.
