Cascades Volcano Observatory The David A. Johnston Cascades Volcano Observatory is the volcano observatory that monitors volcanoes in the northern Cascade Range. Its territory covers Oregon, Washington, and Idaho. The Cascade range's southernmost reaches extend into Northern California, and Cascade volcanoes south of the Oregon-California border—such as Mt. Shasta—previously fell into CVO's jurisdiction. However, as of February 2012, these volcanoes fall under the jurisdiction of the newly formed California Volcano Observatory (CalVO), based in Menlo Park, CA which monitors and researches volcanic activity throughout California and Nevada.

Cascade Range The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at 14411 ft .

Northern California Northern California, often abbreviated NorCal, is the northern portion of the U.S. state of California. Spanning the state's northernmost 48 counties, in contrast to the 10 counties of Southern California, its main population centers include the San Francisco Bay Area (anchored by the cities of San Francisco, San Jose, and Oakland), the Greater Sacramento area (anchored by the state capital Sacramento), and the Metropolitan Fresno area (anchored by the city of Fresno). Northern California also contains redwood forests, along with the Sierra Nevada, including Yosemite Valley and part of Lake Tahoe, Mount Shasta (the second-highest peak in the Cascade Range after Mount Rainier in Washington), and most of the Central Valley, one of the world's most productive agricultural regions.

Mount Larrabee Mount Larrabee is a Skagit Range mountain situated 1.4 mile south of the Canada–United States border, in the North Cascades of Washington state. It is located immediately southeast of American Border Peak within the Mount Baker Wilderness, which is part of the Mount Baker-Snoqualmie National Forest, and near North Cascades National Park. It is notable for its reddish coloring caused by oxidation of Iron in the rock. The rock consists of reddish interbedded and interfolded phyllites and greenstone. Originally known as Red Mountain, the name was changed in 1951 to honor Charles F. Larrabee of the prominent Larrabee family of Bellingham, Washington.

Goat Rocks Goat Rocks is an extinct stratovolcano in the Cascade Range, located between Mount Rainier and Mount Adams in southern Washington, in the United States. Part of the Cascade Volcanoes, it was formed by the subduction of the Juan de Fuca Plate under the western edge of the North American Plate. The volcano was active from 3.2 million years ago until eruptions ceased between 1 and 0.5 million years ago. Throughout its complex eruptive history, volcanism shifted from silicic explosive eruptions to voluminous, mafic activity.
