Mount Shasta (Karuk: Úytaahkoo or "White Mountain": the origin of the name "Shasta" is vague, perhaps from Russian (means "white, clean, pure" means "happiness, luck, fortune, felicity") from the early Russian settlers in California) is located at the southern end of the Cascade Range in Siskiyou County, California and at 14,179 feet is the second highest peak in the Cascades and the fifth highest in California. Mount Shasta has an estimated volume of 85 cubic miles which makes it the most voluminous stratovolcano in the Cascade Volcanic Arc. Photo by Carol Highsmith, 2012.
