Catalina Island, CA Overview

Catalina is primarily composed of two distinct rock units: Catalina Schist from the Early Cretaceous , and Miocene volcanic and intrusive igneous rocks. The island is rich in quartz, to the extent that some beaches on the seaward side have silvery-grey sand.These formations originally occurred on the ocean floor and emerged from the ocean through tectonic activity. This means that the Santa Catalina Island land-mass was never directly connected to mainland California. Other geologic factors that contributed to the island topography observed today include further geologic uplift and subsidence, tectonic plate movement, sedimentation, metamorphic activity, weathering, and erosion.

Santa Catalina Island, often called Catalina Island, or just Catalina, is a rocky island off the coast of the U.S. state of California in the Gulf of Santa Catalina. The island is 22 miles (35 km) long and 8 miles (13 km) across at its greatest width. The island is located about 22 miles (35 km) south-southwest of Los Angeles, California. The highest point on the island is 2,097 feet (639 m) Mt. Orizaba. Part of the Channel Islands of California archipelago, Santa Catalina lies within Los Angeles County.
