My last photo of the looming Mount Shasta in the background. You can see if from an airplane from just about anywhere in northern California. U.S. 395 near Madeline, California is in the center of the photo.

Mount Shasta is a volcano located at the southern end of the Cascade Range in Siskiyou County, California. At 14,179 feet (4,322 m), it is the second highest peak in the Cascades and the fifth highest in California. Mount Shasta has an estimated volume of 85 cubic miles (350 km3) 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, Shasta-Trinity National Forest.

Mount Shasta is not connected to any nearby mountain and dominates the northern California landscape. It rises abruptly and stands nearly 10,000 ft (3,000 m) above the surrounding terrain. On a clear winter day snowy Mount Shasta can be seen from the floor of the Central Valley 140 miles (230 km) south. The mountain has attracted the attention of poets, authors, and presidents.

The mountain consists of four overlapping volcanic cones which have built a complex shape, including the main summit and the prominent satellite cone of 12,330 ft (3,760 m) 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).
