Cascade Mountains

The Cascade Range is a mountainous region famous for its chain of tall volcanoes called the High Cascades that run north-south along the west coast of North America from British Columbia to the Shasta Cascade area of northern California. The small part of the range in British Columbia is called the Cascade Mountains.

The Cascades (as they are called for short) are part of the Pacific Ring of Fire, the ring of volcanoes around the Pacific Ocean. All of the known historic eruptions in the contiguous United States have been from Cascade volcanoes. The two most recent were Lassen Peak in 1914 to 1921 and Mount St. Helens in 1980.

Gregorian Chant

The name is often taken as synonymous with plain chant, comprising not only the Church music of the early Middle Ages, but also later compositions (elaborate melodies for the Ordinary of the Mass, sequences, etc.) written in a similar style down to the sixteenth century and even in modern times. In a stricter sense Gregorian chant means that Roman form of early plain chant as distinguished from the Ambrosian, Galliean, and Mozarabic chants, which were akin to it, but were gradually supplanted by it from the eighth to the eleventh century.
