Joaquin Hills on its way from the Cleveland National Forest to the Pacific Ocean. Wood Canyon is formed by Wood Canyon Creek as it flows south to join Aliso Creek in the center of the park. Another tributary, Sulphur Creek, joins Aliso Creek at the eastern end of the park. Elevations within the park range from above sea level to at Temple Hill in Laguna Beach (colloquially "Top of the World"), on the park's western boundary. On a clear day, most of Orange County can be seen from Temple Hill and the other ridge tops surrounding Aliso Canyon. Aliso and Wood Canyons links two major park systems in Orange County. The South Coast Wilderness, which protects much of the San Joaquin Hills ecosystem, includes Laguna Coast Wilderness Park which borders Aliso and Wood Canyons to the north. The Aliso Creek Corridor, a greenbelt stretching along Aliso Creek to national forest lands in the Santa Ana Mountains, also terminates in Aliso Canyon. Aliso and Wood Canyons very nearly touches the popular Aliso Beach County Park on its southern end; however, the two are separated by the private Ranch at Laguna Beach (formerly Aliso Creek Inn and Golf Course), preventing visitors from accessing the beach using park trails. A plan to extend a public trail through this property was indefinitely suspended in 2009 after the global financial crisis. The park contains a large number of artifacts from past inhabitants of the area. Many types of these prehistoric artifacts are found throughout the park. These include, but are not limited to, open air shell middens, rock shelters, stone tools, and their production sites. There is also historic farm equipment and buildings dating from the Rancho Niguel period. Such historical sites include the Moulton Cement Plant, Bacon House site, and Tischler Rock.
