Geology<br />

Prehistory<br />

During the Miocene and Pliocene periods (5 to 25 million years ago) the Los Angeles<br />

Basin and the surrounding mountains were submerged beneath the Pacific Ocean.<br />

However, movement and collision <strong>of</strong> tectonic plates during the Pleistocene (2 million<br />

years ago) elevated much <strong>of</strong> this area above sea level. This seismic activity eventually<br />

created the land forms that exist today.<br />

Local Geology<br />

The <strong>City</strong> <strong>of</strong> <strong>Inglewood</strong> is located within the Los Angeles basin area, in the southwestern<br />

portion <strong>of</strong> the Transverse Ranges geomorphic province and the northern limits <strong>of</strong> the<br />

Peninsular Range geomorphic province. The Transverse Ranges are an east/westtrending<br />

series <strong>of</strong> steep mountain ranges including the Santa Ynez, Santa Monica, San<br />

Gabriel, and San Bernardino from north to south, respectively. Due to intense<br />

north/south compression, the Transverse Range in this region is one <strong>of</strong> the most rapidly<br />

rising areas on earth. The Peninsular Ranges is characterized by northwest and southwest<br />
