The Shasta Cascade region of California is located in the northeastern and north-central sections of the state bordering Oregon and Nevada, including far northern parts of the Central Valley and the Sierra Nevada mountain range. The area is centered on Mount Shasta in the California Cascade Range, near the Trinity Alps. Mount Shasta is a quiet but scientifically active complex stratovolcano; nearby Lassen Peak has been active as recently as the 20th century.
