Most of the city of Fontana, like its eastern neighbors Rialto and San Bernardino, is built atop a geologically young, gently southward-sloping alluvial fan from nearby Lytle Creek, deposited mainly during the Holocene and late-Pleistocene epochs. There are also sedimentary deposits of similar age from Etiwanda Creek on the western edge of the city. However, the northern and southern edges of the city are formed by the much older San Gabriel and Jurupa mountain ranges, respectively. The Jurupa Mountains are composed primarily of Cretaceous and Paleozoic-era rocks, as are the San Gabriels, which also include even older, Proterozoic formations. The most prominent of the San Gabriel Mountains visible from Fontana is Cucamonga Peak, elevation 8,859 feet (2,700 m). Additionally, the Cucamonga Fault Zone, contiguous with the Sierra Madre Fault Zone, runs through the northern part of the city, along the base of the San Gabriels, notably through the Hunter's Ridge and Coyote Canyon planned communities. It is estimated to be capable of producing earthquakes approximately of magnitude 6.0-7.0.

Local Area Info: Fontana, California

Fontana is a city in San Bernardino County, California. Founded by Azariel Blanchard Miller in 1913, it remained essentially rural until World War II, when entrepreneur Henry J. Kaiser built a large steel mill in the area. It is now a regional hub of the trucking industry, with Interstate 10 and State Route 210 transecting the city from east to west, and Interstate 15 passing diagonally through its northwestern quadrant.

It is home to the largest of the San Bernardino County system libraries, a renovated historic theater, a municipal park, and the Auto Club Speedway on the site of the Kaiser Steel Mill. Fontana also hosts the Fontana Days Half Marathon and 5K run. This race is the fastest half-marathon course in the world.

The United States Census Bureau estimated Fontana's 2017 population at 211,815, making it the second-most populous city in San Bernardino County and the 19th largest in the state. The name fontana is Italian for fountain or water source, being in close proximity to the Santa Ana River to the east.

There are also sedimentary deposits of similar age from Etiwanda Creek on the western edge of the city. However, the northern and southern edges of the city are formed by the much older San Gabriel and Jurupa mountain ranges, respectively.

Additionally, the Cucamonga Fault Zone, contiguous with the Sierra Madre Fault Zone, runs through the northern part of the city, along the base of the San Gabriels, notably through the Hunter's Ridge and Coyote Canyon planned communities. It is estimated to be capable of producing earthquakes approximately of magnitude 6.0-7.0.
