What three states are covered by the volcano range including the North Cascades?
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.
Lake Wenatchee State Park Lake Wenatchee State Park is a publicly owned recreation area located at the eastern end of Lake Wenatchee, a glacier- and snowmelt-fed lake situated in the Wenatchee National Forest on the eastern slopes of the Cascades Mountain Range in the state of Washington. The state park covers 489 acre split into two parts—the north shore park and the south shore park—separated by the Wenatchee River. The park is managed by the Washington State Parks and Recreation Commission.
