Wildcat Canyon

Last updated

Wildcat Canyon is a narrow linear valley just east of the Berkeley Hills in the San Francisco Bay Area, situated in Contra Costa County, California. The canyon is bounded on its east side by the San Pablo Ridge, and is drained by Wildcat Creek which runs northwest to its outlet in San Pablo Bay. Two minor lakes or ponds lie along the creek: Jewel Lake and Lake Anza. The latter was enlarged by the construction of a small dam in the mid-20th century. An active tectonic fault, the Wildcat Fault, runs the length of the canyon. Wildcat Canyon was named for the mountain lions which used to be fairly common in the area. The southern end of the canyon adjacent to the city of Berkeley was incorporated into Tilden Regional Park in the 1930s and remains a major recreation area for local residents. Another regional park, Wildcat Canyon Regional Park, is situated at the northern end of the canyon.

Berkeley Hills

The Berkeley Hills are a range of the Pacific Coast Ranges that overlook the northeast side of the valley that encompasses San Francisco Bay. They were previously called the "Contra Costa Range/Hills", but with the establishment of Berkeley and the University of California, the current usage was applied by geographers and gazetteers.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
