The Transverse Ranges are a mountain range located in southern California, extending from the Pacific Ocean inland. They are characterized by their east-west orientation, which is unusual for most mountain ranges in North America that typically run north-south. This unique alignment is a result of complex geological processes, including tectonic activity. The range includes notable peaks such as Mount San Antonio and Mount Baldy, and is part of the larger California Coast Ranges. The area is rich in biodiversity and features various ecosystems, from coastal scrub to coniferous forests, making it an important region for both wildlife and outdoor recreation.
