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 Inyo Mountains are a short mountain range east of the Sierra Nevada in eastern California in the United States. The range separates the Owens Valley to the west from Saline Valley to the east, extending for approximately 70 miles (110 km) south-southeast from the southern end of the White Mountains, from which they are separated by Westgard Pass, to the east of Owens Lake.
Black Mountain is a summit in the Cleveland National Forest of the Peninsular Ranges in eastern San Diego County, California, north of Ramona. The peak is measured at 4,048 feet (1,234 m), and is sometimes referenced as Big Black Mountain to distinguish it from the smaller Rancho Peñasquitos Black Mountain Open Space Park in the city of San Diego. Black Mountain offers a WX channel for people who wish to tune in on radios to hear the weather; channel is located on VHF frequency 162.4000 MHz.
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.
Big Chico Creek is a creek in northeastern California that originates near Colby Mountain in Lassen National Park. It flows 46 miles (74 km) to its confluence with the Sacramento River in Butte County. The creek's elevation declines from 5,000 feet (1,500 m) above sea level at its head to 120 feet (37 m) where it joins the Sacramento River, as shown on the Ord Ferry USGS quadrangle. Big Chico Creek forms part of the demarcation between the Sierra Nevada and the Cascade Range.
The Klamath Basin is the region in the U.S. states of Oregon and California drained by the Klamath River. It contains most of Klamath County and parts of Lake and Jackson counties in Oregon, and parts of Del Norte, Humboldt, Modoc, Siskiyou, and Trinity counties in California. The 15,751-square-mile (40,790 km2) drainage basin is 35% in Oregon and 65% in California. In Oregon, the watershed typically lies east of the Cascade Range, while California contains most of the river's segment that passes through the mountains. In the Oregon-far northern California segment of the river, the watershed is semi-desert at lower elevations and dry alpine in the upper elevations. In the western part of the basin, in California, however, the climate is more of temperate rainforest, and the Trinity River watershed consists of a more typical alpine climate.
Saint John Mountain is a mountain located in the Northern Coast Ranges of California. It is located just to the north of Snow Mountain in the Mendocino National Forest. The peak is high enough to receive snowfall in winter.
Mount Eddy is the highest peak of the Trinity Mountains, a mountain range of the Klamath Mountains System, located in Siskiyou County, and Trinity County in northern California.
Eagle Peak is located in the Warner Mountains in Modoc County, California, United States. The area is protected in the South Warner Wilderness on the Modoc National Forest. The summit is the highest point in the Warner Mountains and Modoc County. Much of the precipitation that falls on Eagle Peak is snow due to the high elevation of the mountain.
Granite Chief is a mountain located in the Sierra Nevada near Lake Tahoe. The mountain rises to an elevation of 9,010 feet (2,746 m) and receives consistent heavy snowfall during the winter months.
Freel Peak is a mountain located in the Carson Range, a spur of the Sierra Nevada, near Lake Tahoe in California.
Glass Mountain, on the Inyo National Forest, is one of the tallest peaks in Mono County, California. The peak lies 20 miles (32 km) southeast of the shoreline of Mono Lake and is the highest point on the four-mile (6.4 km) long sinuous Glass Mountain Ridge.
The Salmon Mountains are a subrange of the Klamath Mountains in Siskiyou County, northwestern California.
The Marble Mountain Wilderness is a 241,744-acre (978.30 km2) wilderness area located 60 miles (97 km) southwest of Yreka, California, in the United States. It is managed by the United States Forest Service and is within the Klamath National Forest in Siskiyou County. The land was first set aside in April 1931 as the Marble Mountain Primitive Area, which comprised 234,957 acres (950.84 km2). It was one of four areas to gain primitive status under the Forest Service's L-20 regulations that year. In 1964, it became a federally designated wilderness area when the U.S. Congress passed the Wilderness Act.
The Russian Wilderness is a wilderness area of 12,000 acres (49 km2) located approximately 65 miles (105 km) northeast of Eureka in northern California. It is within the Klamath National Forest in Siskiyou County and is managed by the US Forest Service. It was added to the National Wilderness Preservation System when the US Congress passed the California Wilderness Act of 1984.
The Cucamonga Wilderness is a federally designated wilderness area located in the eastern San Gabriel Mountains, in San Bernardino County, Southern California.
The East Fork Salmon River is a 34-mile (55 km) tributary of the Salmon River, flowing through Custer County, Idaho in the United States. It joins the Salmon River about 3.7 miles (6.0 km) east of Clayton and 17 miles (27 km) south-southwest of Challis. The East Fork Salmon River is formed at the confluence of the West Fork East Fork Salmon River and the South Fork East Fork Salmon River between the Boulder and White Cloud mountains in Sawtooth National Recreation Area.
Wooley Creek is a large stream in Siskiyou County, California, a tributary of the Salmon River. Wooley Creek flows 22 miles (35 km) from Man Eaten Lake in the Marble Mountain Wilderness of the Klamath National Forest, in a generally southwest direction, to its confluence with the Salmon River about 4 miles (6.4 km) upstream of the Salmon's confluence with the Klamath River at Somes Bar. The creek drains an isolated and rugged wilderness area – there are no paved roads and only a few permanent residents in its watershed. Lower Wooley Creek provides Class IV-V whitewater and is seldom run due to the lack of easy access. The Wooley Creek Trail provides access along the creek into the wilderness area. It is one of the few major trails in the area suitable for year-round use due to its low elevation.
The North Fork Salmon River is a 36.9-mile (59.4 km) river in Siskiyou County, California. It joins with the South Fork Salmon River at Forks of Salmon to form the Salmon River, a major tributary of the Klamath River. Originating at English Lakes near 7,322-foot (2,232 m) English Peak in the Salmon Mountains, the North Fork drains about 204 square miles (530 km2) of rugged, forested terrain. The entire river is located within the Klamath National Forest, with the headwaters located in the Marble Mountain Wilderness.
The South Fork Salmon River is a 39.5-mile (63.6 km) river in Siskiyou County, California and is the larger of two tributaries that join to form the Salmon River, the other being the North Fork. It begins in the Salmon Mountains, on the border of Siskiyou and Trinity County, about 15 miles (24 km) southeast of Cecilville, and flows generally northwest through the Salmon Mountains to its confluence with the North Fork at Forks of Salmon. The South Fork drains an area of 290 square miles (750 km2), located entirely in the Klamath National Forest, with a significant portion in the Trinity Alps Wilderness.
