Humboldt Redwoods State Park is a state park of California, United States, containing Rockefeller Forest, the world's largest remaining contiguous old-growth forest of coast redwoods. It is located 30 miles (48 km) south of Eureka, California, near Weott in southern Humboldt County, within Northern California, named after the great German nineteenth-century scientist, Alexander von Humboldt. The park was established by the Save the Redwoods League in 1921 largely from lands purchased from the Pacific Lumber Company. Beginning with the dedication of the Raynal Bolling Memorial Grove, it has grown to become the third-largest park in the California State Park system, now containing 51,651 acres (20,902 ha) through acquisitions and gifts to the state.
The Klamath Mountains are a rugged and lightly-populated mountain range in northwestern California and southwestern Oregon in the western United States. As a mountain system within both the greater Pacific Coast Ranges and the California Coast Ranges, the Klamath Mountains have a varied geology, with substantial areas of serpentinite and marble, and a climate characterized by moderately cold winters with very heavy snowfall and warm, very dry summers with limited rainfall, especially in the south. As a consequence of the geology and soil types, the mountains harbor several endemic or near-endemic trees, forming one of the largest collections of conifers in the world. The mountains are also home to a diverse array of fish and animal species, including black bears, large cats, owls, eagles, and several species of Pacific salmon. Millions of acres in the mountains are managed by the United States Forest Service. The northernmost and largest sub-range of the Klamath Mountains are the Siskiyou Mountains.
The Eel River is a major river, about 196 miles (315 km) long, in northwestern California. The river and its tributaries form the third-largest watershed entirely in California, draining a rugged area of 3,684 square miles (9,540 km2) in five counties. The river flows generally northward through the Coast Ranges west of the Sacramento Valley, emptying into the Pacific Ocean about 10 miles (16 km) downstream from Fortuna and just south of Humboldt Bay. The river provides groundwater recharge, recreation, and industrial, agricultural and municipal water supply.
The Avenue of the Giants is a scenic highway in northern California, United States, running through Humboldt Redwoods State Park. It is named after the coastal redwoods that tower over the route. The road is a former alignment of U.S. Route 101, and continues to be maintained as a state highway as State Route 254.
The Trinity Alps are a mountain range in Trinity County and Siskiyou County in Northern California. They are a subrange of the Klamath Mountains located to the north of Weaverville.
The Northern California coastal forests are a temperate coniferous forests ecoregion of coastal Northern California and southwestern Oregon.
The Shasta–Trinity National Forest is a federally designated forest in northern California, United States. It is the largest National Forest in California and is managed by the U.S. Forest Service. The 2,210,485 acre forest encompasses five wilderness areas, hundreds of mountain lakes and 6,278 miles (10,103 km) of streams and rivers. Major features include Shasta Lake, the largest man-made lake in California and Mount Shasta, elevation 14,179 feet (4,322 m).
The Six Rivers National Forest is a U.S. National Forest located in the northwestern corner of California. It was established on June 3, 1947 by U.S. President Harry S. Truman from portions of Klamath, Siskiyou and Trinity National Forests. Its over one million acres (4,000 km2) of land contain a variety of ecosystems and 137,000 acres (550 km2) of old growth forest. It lies in parts of four counties; in descending order of forestland area they are Del Norte, Humboldt, Trinity, and Siskiyou counties. The forest is named after the Eel, Van Duzen, Klamath, Trinity, Mad, and Smith rivers, which pass through or near the forest's boundaries.
The Lost Coast is a mostly natural and undeveloped area of the California North Coast in Humboldt and Mendocino Counties, which includes the King Range. It was named the "Lost Coast" after the area experienced depopulation in the 1930s. In addition, the steepness and related geotechnical challenges of the coastal mountains made this stretch of coastline too costly for state highway or county road builders to establish routes through the area, leaving it the most undeveloped and remote portion of the California coast. Without any major highways, communities in the Lost Coast region such as Petrolia, Shelter Cove, and Whitethorn are somewhat isolated from the rest of California.
The King Range is a mountain range of the Outer Northern California Coast Ranges System, located entirely within Humboldt County on the North Coast of California.
The Coast Ranges of California span 400 miles (644 km) from Del Norte or Humboldt County, California, south to Santa Barbara County. The other three coastal California mountain ranges are the Transverse Ranges, Peninsular Ranges and the Klamath Mountains.
The North Coast of California is a region in Northern California that lies on the Pacific coast between San Francisco Bay and the Oregon border. It commonly includes Mendocino, Humboldt, and Del Norte counties and sometimes includes Lake and two counties from the San Francisco Bay area, Marin and Sonoma.
Petrolia is an unincorporated community in Humboldt County, California, 10 miles (16 km) southeast of Cape Mendocino, at an elevation of 121 feet (37 m) above sea level, within ZIP Code 95558, and area code 707. Petrolia was the site of the first oil well drilled in California.
The Ventana Wilderness of Los Padres National Forest is a federally designated wilderness area located in the Santa Lucia Range along the Central Coast of California. This wilderness was established in 1969 when the Ventana Wilderness Act redesignated the 55,800-acre (22,600 ha) Ventana Primitive Area as the Ventana Wilderness and added land, totalling 98,000 acres. In 1978, the Endangered American Wilderness Act added 61,000 acres, increasing the total wilderness area to about 159,000 acres. The California Wilderness Act of 1984 added about 2,750 acres. The Los Padres Condor Range and River Protection Act of 1992 created the approximately 14,500-acre (5,900 ha) Silver Peak Wilderness and added about 38,800 acres to the Ventana Wilderness in addition to designating the Big Sur River as a Wild and Scenic River. The Big Sur Wilderness and Conservation Act of 2002 expanded the wilderness for the fifth time, adding nearly 35,000 acres (14,000 ha), increasing the total acreage of the wilderness to its present size of 240,026 acres (97,135 ha).
The Snow Mountain Wilderness is a 60,076-acre (243.12 km2) federally designated wilderness area located 65 miles (105 km) north of Santa Rosa, California, USA in the Mendocino National Forest. The U.S. Congress passed the California Wilderness Act of 1984 which created 23 new wilderness areas including Snow Mountain. It lies within the North Coast Range of mountains.
The Coast Range ecoregion is a Level III ecoregion designated by the Environmental Protection Agency (EPA) in the U.S. states of Washington, Oregon, and California. It stretches along the Pacific Coast from the tip of the Olympic Peninsula in the north to the San Francisco Bay in the south, including Grays Harbor, Willapa Bay, and the Long Beach Peninsula in Washington, the entire length of the Oregon Coast, and the Northern California Coast. Named for the Coast Range mountains, it encompasses the lower elevations of the Olympic Mountains, the Oregon Coast Range, the Californian North Coast Ranges, and surrounding lowlands.
The Yolla Bolly–Middle Eel Wilderness is a federally designated wilderness area in the Yolla Bolly Range of the southern Klamath Mountains and the Inner Northern California Coast Ranges, in Northern California.
The South Fork Eel River is the largest tributary of the Eel River in north-central California in the United States. The river flows 105 miles (169 km) north from Laytonville to Dyerville/Founders' Grove where it joins the Eel River. The South Fork drains a long and narrow portion of the Coast Range of California in parts of Mendocino and Humboldt counties. U.S. Route 101 follows the river for much of its length.
The North Fork Eel River is the smallest of four major tributaries of the Eel River in northwestern California in the United States. It drains a rugged wilderness area of about 286 square miles (740 km2) in the California Coast Ranges, and flows through national forests for much of its length. Very few people inhabit the relatively pristine watershed of the river; there are no operational stream gauges and only one bridge that crosses the river, near the boundary between Trinity and Mendocino Counties.
The South Fork Eel River Wilderness is a 12,868-acre (5,207 ha) wilderness area located in Mendocino County, California. The wilderness was added to the National Wilderness Preservation System when the United States Congress passed the Northern California Coastal Wild Heritage Wilderness Act in 2006. The Department of the Interior's Bureau of Land Management (BLM) is the agency in charge.
