Rainbow Mountain, Stratovolcano in Siskiyou County, California, United States.
Rainbow Mountain is a stratovolcano in the southern Cascade Range situated between Mount Shasta and Medicine Lake Volcano. The peak rises to about 7,619 feet and displays the characteristic layered structure created by countless eruption cycles over its long geological history.
The volcano formed during the Early Pleistocene period through repeated eruptions of andesitic and dacitic rock. Its development spans millions of years of sustained volcanic building.
Native American tribes of Siskiyou County incorporated the mountain landscape into their traditional practices for gathering resources and spiritual ceremonies.
Hiking trails remain snow covered during winter months, making summer the ideal season for a visit. Plan to start early in the day and come prepared for weather changes that develop quickly at higher elevations.
The mountain ranks among the highest peaks in the area and offers views across multiple national forest territories from its summit. This position allows hikers to take in the diversity of volcanic landscapes in the region all at once.
