The Thousand Lakes Wilderness is located within the southern portion of the Cascade Range in northeastern California. The 16,335-acre (66 km2) wilderness was established in 1964 with the passage of the Wilderness Act and is administered by Lassen National Forest. The area lies within Shasta County, midway between the town of Burney and Lassen Volcanic National Park.
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 14,411 feet (4,392 m).
The Wilderness Act of 1964 was written by Howard Zahniser of The Wilderness Society. It created the legal definition of wilderness in the United States, and protected 9.1 million acres (37,000 km²) of federal land. The result of a long effort to protect federal wilderness and to create a formal mechanism for designating wilderness, the Wilderness Act was signed into law by President Lyndon B. Johnson on September 3, 1964 after over sixty drafts and eight years of work.
Lassen National Forest is a United States national forest of 1,700 square miles (4,300 km2) in northeastern California. It is named after pioneer Peter Lassen, who mined, ranched and promoted the area to emigrant parties in the 1850s.
Volcanic activity and glaciers have combined to create the current topography. The area is dominated by Crater Peak (8677 ft), the highest point in the Lassen National Forest. The lowest point in the wilderness, 5546 feet, occurs at the base of the volcano. This peak is a reminder of the glacial action that eroded the original, much larger Thousand Lakes Volcano and created the many small lakes and ponds scattered through the region. Some of the volcanic activity is relatively recent—Hall Butte is cinder cone that erupted perhaps 500 years ago.
Despite its name, there are considerably fewer than a thousand lakes—about seven major lakes lie within the wilderness. The largest is Eiler Lake, named after Lu Eiler the person who discovered Thousand Lakes Valley. All of the larger lakes contain populations of trout. Wildlife includes black-tailed deer, black bear, pika, pine marten, northern goshawk, spotted owl, pileated woodpecker, and Clark's nutcracker. Even elk have been known to visit occasionally.
Two forms of black-tailed deer or blacktail deer that occupy coastal woodlands in the Pacific Northwest of North America are subspecies of the mule deer. They have sometimes been treated as a species, but virtually all recent authorities maintain they are subspecies. The Columbian black-tailed deer is found in western North America, from Northern California into the Pacific Northwest of the United States and coastal British Columbia in Canada. The Sitka deer is found coastally in British Columbia, southeast Alaska, and southcentral Alaska.
A pika is a small mountain-dwelling mammal found in Asia and North America. With short limbs, very round body, and even coat of fur, and no external tail, they resemble their close cousin the rabbit, but with short rounded ears. The large-eared pika of the Himalayas and nearby mountains is found at heights of more than 6,000 metres (20,000 ft), among the highest of any mammal.
The northern goshawk is a medium-large raptor in the family Accipitridae, which also includes other extant diurnal raptors, such as eagles, buzzards and harriers. As a species in the genus Accipiter, the goshawk is often considered a "true hawk". The scientific name is Latin; Accipiter is "hawk", from accipere, "to grasp", and gentilis is "noble" or "gentle" because in the Middle Ages only the nobility were permitted to fly goshawks for falconry.
There are four trailheads providing access into the wilderness and approximately 21 miles (34 km) of trails.
Lassen Volcanic National Park is an American national park in northeastern California. The dominant feature of the park is Lassen Peak, the largest plug dome volcano in the world and the southernmost volcano in the Cascade Range. Lassen Volcanic National Park started as two separate national monuments designated by President Theodore Roosevelt in 1907: Cinder Cone National Monument and Lassen Peak National Monument.
The geology of the Lassen volcanic area presents a record of sedimentation and volcanic activity in the area in and around Lassen Volcanic National Park in Northern California, U.S. The park is located in the southernmost part of the Cascade Mountain Range in the Pacific Northwest region of the United States. Pacific Oceanic tectonic plates have plunged below the North American Plate in this part of North America for hundreds of millions of years. Heat from these subducting plates has fed scores of volcanoes in California, Oregon, Washington and British Columbia over at least the past 30 million years and is also responsible for activities in the Lassen volcanic area.
Lassen Peak, commonly referred to as Mount Lassen, is the southernmost active volcano in the Cascade Range of the Western United States. Located in the Shasta Cascade region of Northern California, it is part of the Cascade Volcanic Arc, which stretches from southwestern British Columbia to northern California. Lassen Peak reaches an elevation of 10,457 feet (3,187 m), standing above the northern Sacramento Valley. It supports many flora and fauna among its diverse habitats, which are subject to frequent snowfall and reach high elevations.
The geothermal areas in Lassen Volcanic National Park include several groups of hot springs and fumaroles, as remnants of former volcanic activity, exist in Lassen Volcanic National Park. Most of these lie in or are closely adjacent to Mount Tehama's caldera. Bumpass Hell is the most spectacular of these, but others of importance are Sulphur Works, Little Hot Springs Valley, Boiling Springs Lake and Devil's Kitchen. In each thermal area, the highest temperature of water generally is close to the boiling temperature at the altitude of the particular spring or fumarole — 198 °F (92 °C) at Bumpass Hell and 191 °F (88 °C) on the northwest flanks of Lassen Peak. Temperatures as high as 230 °F (110 °C) have been recorded in the park.
Chaos Crags is the youngest group of lava domes in Lassen Volcanic National Park, California. They formed as six dacite domes 1,100-1,000 years ago, one dome collapsing during an explosive eruption about 70 years later. The eruptions at the Chaos Crags mark one of just three instances of Holocene activity within the Lassen volcanic center. The cluster of domes is located north of Lassen Peak and form part of the southernmost segment of the Cascade Range in Northern California. Each year, a lake forms at the base of the Crags, and typically dries by the end of the summer season.
Cinder Cone is a cinder cone volcano in Lassen Volcanic National Park within the United States. It is located about 10 miles (16 km) northeast of Lassen Peak and provides an excellent view of Brokeoff Mountain, Lassen Peak, and Chaos Crags.
Mount Jefferson is a stratovolcano in the Cascade Volcanic Arc, part of the Cascade Range in the U.S. state of Oregon. The second highest mountain in Oregon, it is situated within Linn County, Jefferson County, and Marion County and forms part of the Mount Jefferson Wilderness. Due to the ruggedness of its surroundings, the mountain is one of the hardest volcanoes to reach in the Cascades. It is also a popular tourist destination despite its remoteness, with recreational activities including hiking, backpacking, mountaineering, and photography. Vegetation at Mount Jefferson is dominated by Douglas fir, silver fir, mountain hemlock, ponderosa pine, lodgepole pine, and several cedar species. Carnivores, insectivores, bats, rodents, deer, birds, and various other species inhabit the area.
Mount Thielsen, or Big Cowhorn, is an extinct shield volcano in the Oregon High Cascades, near Mount Bailey. Because eruptive activity ceased 250,000 years ago, glaciers have heavily eroded the volcano's structure, creating precipitous slopes and a horn-like peak. The spire-like shape of Thielsen attracts lightning strikes and creates fulgurite, an unusual mineral. The prominent horn forms a centerpiece for the Mount Thielsen Wilderness, a reserve for recreational activities such as skiing and hiking.
Mount McLoughlin is a steep-sided stratovolcano, or composite volcano, in the Cascade Range of southern Oregon and within the Sky Lakes Wilderness. It is one of the volcanic peaks in the Cascade Volcanic Arc, within the High Cascades sector. A prominent landmark for the Rogue River Valley, the mountain is north of Mount Shasta, and Crater Lake lies to the north-northeast. It was named around 1838 after John McLoughlin, a Chief Factor for the Hudson's Bay Company. McLouglin's prominence has made it a landmark to Native American populations for thousands of years.
Indian Heaven is a volcanic field in Skamania County in the state of Washington, in the United States. Midway between Mount St. Helens and Mount Adams, the field dates from the Pleistocene to the early Holocene epoch. It trends north to south and is dominated by six small shield volcanoes; these shields are topped by small spatter and cinder cones, and the field includes a number of subglacial volcanoes and tuyas. The northernmost peak in the field is Sawtooth Mountain and the southernmost is Red Mountain; its highest point is Lemei Rock at an elevation of 5,925 feet (1,806 m).
Brokeoff Volcano is an eroded andesitic stratovolcano in the Cascade Volcanic Arc and the Cascade Range in Northern California. Part of the Lassen volcanic area, its highest remaining remnant, Brokeoff Mountain, is itself the second highest peak in Lassen Volcanic National Park and connects to the park's highest point, Lassen Peak. Located on the border of Tehama County and Shasta County, Brokeoff's peak is the highest point in the former. The hikers that summit this mountain each year are treated to "exceptional" views of Lassen Peak, the Central Valley of California, and many of the park's other features. On clear days, Mount Shasta can also be seen in the distance.
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.
The Shasta–Trinity National Forests are federally designated forests in northern California, USA. Combined, they are the largest National Forest in California and are managed by the U.S. Forest Service. The 2,210,485 acre combined-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 Volcanic Legacy Scenic Byway is a scenic highway and All-American Road in the U.S. states of California and Oregon. It is roughly 500 miles (804.7 km) long and travels north–south along the Cascade Range past numerous volcanoes. It is composed of two separate National Scenic Byways, the Volcanic Legacy Scenic Byway - Oregon and Volcanic Legacy Scenic Byway - California. The latter also wholly includes the Lassen Scenic Byway.
Gearhart Mountain Wilderness is a wilderness area located within the Fremont–Winema National Forest in Lake County and Klamath County in south-central Oregon. This area was established in 1943 as a Wild Area and designated as wilderness with the Wilderness Act of 1964. In 1984, an additional 4,144 acres (1,677 ha) were added for a total of 22,823 acres (9,236 ha). The wilderness is entirely within the Bly Ranger District.
The South Warner Wilderness is a federally designated wilderness area 12 miles (19 km) east of Alturas, California, USA. It encompasses more than 70,000 acres (283 km2) of the Warner Mountains. It is within the Modoc National Forest and managed by the US Forest Service. Elevations range from 5,000 feet (1,500 m) to 9,895 feet at Eagle Peak.
The Caribou Wilderness is a federally designated wilderness area created by the Wilderness Act of 1964 and is part of the National Wilderness Preservation System. It is located 60 miles (97 km) east of Redding in the state of California, USA. The Caribou Wilderness comprises 20,546 acres (83.15 km2) and is adjacent to the east side of Lassen Volcanic National Park. Although the park is surrounded by Lassen National Forest, it is managed separately by the National Park Service, whereas the U.S. Forest Service manages the wilderness.
