Mt Shasta is a potentially active volcano located at the southern end of the Cascade Range in Siskiyou County, California. It towers at 14,179 feet and is the second highest peak in the Cascades and the fifth highest in California. Mt Shasta has an estimated volume of 85 cubic miles which makes it the most voluminous stratovolcano in the Cascade Volcanic Arc and a expert rated trip for mountain climbers and trekking enthusiast.
Mount Shasta is connected to nearby Shastina, and they dominate the northern California landscape. It rises abruptly and stands nearly 10,000 ft above the surrounding terrain. The mountain has attracted the attention of poets, authors, and presidents and of course…trekkers. The mountain consists of four overlapping volcanic cones that have built a complex shape, including the main summit and the prominent satellite cone of 12,330 ft Shastina, which has a visibly conical form. If Shastina were a separate mountain, it would rank as the fourth-highest peak of the Cascade Range.
Over the last 10,000 years, Mount Shasta has erupted an average of every 800 years, but in the past 4,500 years the volcano has erupted an average of every 600 years. The last significant eruption on Mount Shasta may have occurred about two centuries ago. Mt Shasta can release volcanic ash, pyroclastic flows and andesite lava. Its deposits can be detected under nearby small towns totaling 20,000 in population. Mount Shasta has an explosive, eruptive history. There are fumaroles on the mountain, which show that Mt Shasta is still very much alive!
