The San Emigdio Mountains are a part of the Transverse Ranges in Southern California, extending from Interstate 5 at Lebec and Gorman on the east to Highway 33–166 on the west. They link the Tehachapis and Temblor Range and form the southern wall of the San Joaquin Valley. The range is named after Emygdius, an early Christian martyr.
Santiago Peak is the southern mountain of the Saddleback landform in Orange County and Riverside County, California. It is the highest and most prominent peak of both the Santa Ana Mountains and Orange County. The peak is named for Santiago Creek, which begins on its southwestern slope. During most winters, snow falls at least once on the peak. A telecommunication antenna farm with microwave antennas sits atop the peak.
Basin Mountain is a mountain in the Great Range of the Adirondacks in the U.S. state of New York. It is the ninth-highest peak in New York, with an elevation of 4,827 feet (1,471 m), and one of the 46 High Peaks in Adirondack Park. It is located in the town of Keene in Essex County. The peak was named either for the basins formed between knobs on its slopes or the large basin to its southeast formed by it and the surrounding mountains. The name Basin was most likely coined by Orson Schofield Phelps and Frederick W. Perkins in 1857 during an ascent of Mount Marcy. The earliest appearance of the name in writing was made by surveyor Verplanck Colvin in 1873.
Rancho Santiago de Santa Ana was a 63,414-acre (256.63 km2) Spanish land concession in present-day Orange County, California, given by Spanish Alta California Governor José Joaquín de Arrillaga in 1810 to Jose Antonio Yorba and his nephew Pablo Peralta.

Cañada Gobernadora is a tributary to San Juan Creek, about 8.5 miles (13.7 km) long, in southern Orange County in the U.S. state of California. The creek begins in the foothills of the Santa Ana Mountains, at an elevation of 1,040 feet (320 m), and flows south through residential, agricultural and finally undeveloped land, to its confluence with San Juan Creek a few miles upstream of the city of San Juan Capistrano. The upper half of the stream is largely channelized and flows through golf courses, while the lower half is a wash-like channel that can be up to 700 feet (210 m) wide. The stream receives some urban runoff from the residential communities higher in its watershed. The watershed includes several geologic formations, including the Tertiary Sespe Formation and Santiago Formation, and Holocene sedimentary and alluvial deposits embedded in its narrow floodplain. Cañada Gobernadora forms an unofficial dividing line for the lower portion of the San Juan watershed; most urban development is confined to west of the creek's valley, while agricultural and undeveloped lands lie to the east of the creek.
San Mateo Creek is a stream in Southern California in the United States, whose watershed mostly straddles the border of Orange and San Diego Counties. It is about 22 miles (35 km) long, flowing in a generally southwesterly direction.

Silverado Canyon is a roughly 2,500-foot-deep gorge in the Santa Ana Mountains, in the U.S. state of California. The small stream it is associated with, Silverado Creek, rises on the north slope of Modjeska Peak at the elevation of 3,980 feet (1,210 m) and flows north and west, past the town of Silverado to join Santiago Creek at 942 feet (287 m) after a journey of just under 5 miles (8.0 km). The main branch, Ladd Canyon, is just over 3 miles (4.8 km) long. Its stream arises on the east flank of Pleasants Peak at about 3,590 feet (1,090 m) and flows southwest into the main stem at about 1,178 feet (359 m) near Silverado. They are part of the Santa Ana River watershed. A hiking trail/fire road runs the entire length of the canyon.
Villa Park Dam is an embankment dam on Santiago Creek in Orange County, California in the United States. Along with the upstream Santiago Dam, the dam serves primarily for flood control for the cities of Villa Park, Orange, Tustin and Santa Ana and also regulates the inflow of Santiago Creek into the Santa Ana River. Construction was completed in 1963, and the dam is owned by the County of Orange.
The Temescal Mountains, also known as the Sierra Temescal, are one of the northernmost mountain ranges of the Peninsular Ranges in western Riverside County, in Southern California in the United States. They extend for approximately 25 mi (40 km) southeast of the Santa Ana River east of the Elsinore Fault Zone to the Temecula Basin and form the western edge of the Perris Block.
Oak Mountain is a mountain in the northern Peninsular Ranges System, in Riverside County, in southern California.
Puhú was a major residential village in the Santa Ana Mountains shared by the Tongva, Acjachemen, Payómkawichum, and Serrano near Santiago Peak. The village resided approximately 600m above sea level in the upper areas of the Black Star Canyon. The village was at its height from the years 1220–1770. The village retained its multi-seasonal occupancy and economic and political systems up until its destruction and a communal massacre in 1832.
Temple Hill is the second highest peak in the San Joaquin Hills area of Orange County, California, United States. Its elevation is 1,038 feet (316 m).

It dominates the southern portion of Laguna Beach between downtown and Aliso Creek. The summit provides views of Saddleback Valley to the east, the Pacific Ocean to the south, and most of Orange County up to the San Gabriel Mountains to the north.
