Geologic Gems of California's State Parks
STATE OF CALIFORNIA – EDMUND G. BROWN JR., GOVERNOR NATURAL RESOURCES AGENCY – JOHN LAIRD, SECRETARY CALIFORNIA GEOLOGICAL SURVEY DEPARTMENT OF PARKS AND RECREATION – LISA MANGAT, DIRECTOR JOHN D. PARRISH, Ph.D., STATE GEOLOGIST DEPARTMENT OF CONSERVATION – DAVID BUNN, DIRECTOR PLATE 1 The rugged cliffs of Del Norte Coast Redwoods State Park are composed of some of California’s Bio-regions the most tortured, twisted, and mobile rocks of the North American continent. The California’s Geomorphic Provinces rocks are mostly buried beneath soils and covered by vigorous redwood forests, which thrive in a climate famous for summer fog and powerful winter storms. The rocks only reveal themselves in steep stream banks, along road and trail cut banks, along the precipitous coastal cliffs and offshore in the form of towering rock monuments or sea stacks. (Photograph by CalTrans staff.) Few of California’s State parks display impressive monoliths adorned like a Patrick’s Point State Park displays a snapshot of geologic processes that have castle with towering spires and few permit rock climbing. Castle Crags State shaped the face of western North America, and that continue today. The rocks Park is an exception. The scenic beauty is best enjoyed from a distant exposed in the seacliffs and offshore represent dynamic interplay between the vantage point where one can see the range of surrounding landforms. The The Klamath Mountains consist of several rugged ranges and deep canyons. Klamath/North Coast Bioregion San Joaquin Valley Colorado Desert subducting oceanic tectonic plate (Gorda Plate) and the continental North American monolith and its surroundings are a microcosm of the Klamath Mountains The mountains reach elevations of 6,000 to 8,000 feet. -
Final Environmental Impact Statement
Final Environmental Impact Statement Elwha River Ecosystem Restoration Implementation Purpose and Need: The Elwha River ecosystem and native anadromous fisheries are severely degraded as a result of two hydroelectric dams (projects) and their reservoirs built in the early 1900s. Congress has mandated the full restoration of this ecosystem and its native anadromous fisheries through the Elwha River Ecosystem and Fisheries Restoration Act (Public Law 102-495). The Department of the Interior has found there is a need to return this river and the ecosystem to its natural, self-regulating state, and proposes to implement the Congressional mandate by removing both dams in a safe, environmentally sound and cost effective manner and implementing fisheries and ecosystem restoration planning. Only dam removal would fully restore the ecosystem or its native anadromous fisheries. Proposed Action: The U.S. Department of the Interior proposes to fully restore the Elwha River ecosystem and native anadromous fisheries through the removal of Elwha Dam and Glines Canyon Dam and implementing fish restoration and revegetation. Dam removal would occur over a 2-year period. Elwha Dam would be removed by blasting, and Glines Canyon Dam by a combination of blasting and diamond wire saw cutting. Lake Aldwell would be drained by a diversion channel, and Lake Mills by notching down Glines Canyon Dam. Stored sediment would be eroded naturally by the Elwha River. The proposed action is located in Clallam County, on the Olympic Peninsula, in Washington State. Lead/Cooperating agencies: The National Park Service is the lead agency.
