PLEISTOCENE. 
GENERAL CHARACTER. 
The Pleistocene deposits in the Los Angeles region comprise gravel, 
sand, and clay, the first mentioned predominating. The gravel and 
sand capping the Fernando in the region of the oil belt and farther 
south, especially on the top of the ridge on which the normal school 
is situated, are probably of marine origin; the rest of the deposits are 
largely fluviatile.
