Mount Shasta is a potentially active volcano at the southern end of the Cascade Range in Siskiyou County, in the U.S. state of California. At an elevation of 4321.8m, it is the second-highest peak in the Cascades and the fifth-highest in California. Mount Shasta has an estimated volume of 85mi3, which makes it the most voluminous stratovolcano in the Cascade Volcanic Arc.The mountain and its surrounding area are managed by the U.S. Forest Service as part of the Shasta–Trinity National Forest.DescriptionMount Shasta is connected to nearby Shastina, and they dominate the northern California landscape. It rises abruptly and stands nearly 10000ft above the surrounding terrain. On a clear winter day, snowy Mount Shasta can be seen from the floor of the Central Valley 140mi to the south. The mountain has attracted the attention of poets, authors, and presidents.The mountain consists of four overlapping volcanic cones that have built a complex shape, including the main summit and the prominent satellite cone of 12330ft 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 (after Mount Rainier, Rainier's Liberty Cap, and Mount Shasta itself).
