Silverado Canyon is a roughly 2,500-foot-deep (760 m) gorge in the Santa Ana Mountains, in the U.S. state of California.[1] 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)[1] 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)[2] near Silverado. They are part of the Santa Ana River watershed. A hiking trail/fire road runs the entire length of the canyon.
