From the 1850s through the 1860s, the United States Coast Survey, now NOAA's Office of Coast Survey, published a set of color maps with five stratigraphic units detailing the geologic makeup of California as well as a comprehensive set of nautical charts for the entire coast of California. [14]
The California chaparral and woodlands ecoregion has a great range of plant communities in the Southern Coast Ranges, including mixed evergreen forests, oak woodland and savannas, grasslands, northern coastal scrub, and the Monterey Pine woodlands of the Monterey Peninsula and two other coastal enclaves of the Santa Lucia Range.

Ever since it began operations, the Coast Survey had faced hostility from politicians who believed that it should complete its work and be abolished as a means of reducing U.S. government expenditures, and Hassler and Bache had fought back periodic attempts to cut its funding.
Map of California topography and geomorphic provinces California's major mountain ranges. California is a U.S. state on the western coast of North America.Covering an area of 163,696 sq mi (423,970 km 2), California is among the most geographically diverse states.
Coastal California is heavily influenced by east–west distances to the dominant cold California Current as well as microclimates.Due to hills and coast ranges having strong meteorological effects, summer and winter temperatures (other than occasional heat waves) are heavily moderated by ocean currents and fog with strong seasonal lags compared to interior valleys as little as 10 mi (16 km) away.
The USGS Coastal and Marine Science Center (formerly the USGS Center for Coastal Geology) has three sites, one for the Atlantic Ocean (located in Woods Hole, Massachusetts), one for the Pacific Ocean (located in Santa Cruz, California) and one for the Gulf of Mexico (located on the University of South Florida's St. Petersburg campus). The goal ...
The oldest rocks in California date back 1.8 billion years to the Proterozoic and are found in the San Gabriel Mountains, San Bernardino Mountains, and Mojave Desert.The rocks of eastern California formed a shallow continental shelf, with massive deposition of limestone during the Paleozoic, and sediments from this time are common in the Sierra Nevada, Klamath Mountains and eastern Transverse ...
150 photos included in The California Coast from the Air (2014) by Gary Griggs and Deepika Shrestha Ross. [12] Photos of Fort Funston near San Francisco were used by the U.S. Geological Survey (USGS) to test a method of calculating the amount of coastal erosion. [13] [14]
