The Mount Zirkel Wilderness is a U.S. Wilderness Area located in Routt National Forest in northwest Colorado. The closest city is Steamboat Springs, Colorado. The wilderness is named after Mount Zirkel, the highest peak in the range at 12,182 feet (3,713 m), which itself is named after German geologist Ferdinand Zirkel.
Some areas within the wilderness display bedrock composed of metamorphic schists with large garnet crystals.
Most of the wilderness is blanketed in dense spruce-fir forests, although it also contains alpine tundra, montane forest, meadow, and riparian habitats.
The southern portion of the wilderness is largely made up of a unique habitat called ribbon forest, formed when large amounts of snow and wind keep tree growth restricted to north-south bands of trees, mostly about twenty feet across. The Buffalo Pass and Mad Creek regions receive more snowfall than anywhere else in Colorado. The central portion contains the wilderness's highest peaks and encompasses alpine tundra. North of this, the lower elevations of the Encampment River headwaters are covered in dense lodgepole pine and spruce-fir forest, which was partially burned in the Beaver Creek Fire of summer 2016.
Olympic National Park is a United States national park located in the State of Washington, on the Olympic Peninsula. The park has four regions: the Pacific coastline, alpine areas, the west-side temperate rainforest, and the forests of the drier east side. Within the park there are three distinct ecosystems, including subalpine forest and wildflower meadow, temperate forest, and the rugged Pacific coast.
Rocky Mountain National Park is an American national park located approximately 76 mi (122 km) northwest of Denver International Airport in north-central Colorado, within the Front Range of the Rocky Mountains. The park is situated between the towns of Estes Park to the east and Grand Lake to the west. The eastern and western slopes of the Continental Divide run directly through the center of the park with the headwaters of the Colorado River located in the park's northwestern region. The main features of the park include mountains, alpine lakes and a wide variety of wildlife within various climates and environments, from wooded forests to mountain tundra.
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.
Mount Evans is the highest peak in the namesake Mount Evans Wilderness in the Front Range of the Rocky Mountains of North America. The prominent 14,271-foot fourteener is located 13.4 miles (21.6 km) southwest by south of Idaho Springs in Clear Creek County, Colorado, United States, on the drainage divide between Arapaho National Forest and Pike National Forest.
The San Francisco Peaks are a volcanic mountain range in San Francisco volcanic field in north central Arizona, just north of Flagstaff and a remnant of the former San Francisco Mountain. The highest summit in the range, Humphreys Peak, is the highest point in the state of Arizona at 12,633 feet (3,851 m) in elevation. The San Francisco Peaks are the remains of an eroded stratovolcano. An aquifer within the caldera supplies much of Flagstaff's water while the mountain itself is in the Coconino National Forest, a popular recreation site. The Arizona Snowbowl ski area is on the western slopes of Humphreys Peak, and has been the subject of major controversy involving several tribes and environmental groups.
The Trinity Alps are a mountain range in Siskiyou County and Trinity County, in Northern California. They are a subrange of the Klamath Mountains and located to the north of Weaverville.
The Powderhorn Wilderness is a 62,050-acre (251.1 km2) wilderness area in Hinsdale and Gunnison Counties, Colorado, USA, located 5 miles (8.0 km) northeast of Lake City. Most of the northern part of the area, 48,115 acres (194.71 km2), about 77.5%, is located on Bureau of Land Management land and its southern portion, 13,935 acres (56.39 km2), about 22.5%, is located within the Gunnison National Forest. Elevations in the wilderness range from 8,500 feet (2,600 m) at the West Fork Powderhorn Creek to 12,661 feet (3,859 m) at the summit of Calf Creek Plateau.
The Coconino National Forest is a 1.856-million acre United States National Forest located in northern Arizona in the vicinity of Flagstaff. Originally established in 1898 as the "San Francisco Mountains National Forest Reserve", the area was designated a U.S. National Forest in 1908 when the San Francisco Mountains National Forest Reserve was merged with lands from other surrounding forest reserves to create the Coconino National Forest. Today, the Coconino National Forest contains diverse landscapes, including deserts, ponderosa pine forests, flatlands, mesas, alpine tundra, and ancient volcanic peaks. The forest surrounds the towns of Sedona and Flagstaff and borders four other national forests; the Kaibab National Forest to the west and northwest, the Prescott National Forest to the southwest, the Tonto National Forest to the south, and the Apache-Sitgreaves National Forest to the southeast. The forest contains all or parts of ten designated wilderness areas, including the Kachina Peaks Wilderness, which includes the summit of the San Francisco Peaks. The headquarters are in Flagstaff. There are local ranger district offices in Flagstaff, Happy Jack, and Sedona.
The Hells Canyon Wilderness is a wilderness area in the western United States, in Idaho and Oregon. Created 46 years ago in 1975, the Wilderness is managed by both the U.S. Bureau of Land Management and the U.S. Forest Service and contains some of the most spectacular sections of the Snake River as it winds its way through Hells Canyon, North America's deepest river gorge and one of the deepest gorges on Earth. The Oregon Wilderness Act of 1984 added additional acreage and currently the area protects a total area of 217,927 acres (88,192 ha). It lies entirely within the Hells Canyon National Recreation Area except for a small 946-acre (383 ha) plot in southeastern Wallowa County, Oregon which is administered by the Bureau of Land Management. The area that is administered by the Forest Service consists of portions of the Wallowa, Nez Perce, Payette, and Whitman National Forests.
The Coeur d'Alene Mountains are the northwesternmost portion of the Bitterroot Range, part of the Rocky Mountains, located in northern Idaho and westernmost Montana in the Western United States.
The Purcell Wilderness Conservancy is a provincial park in British Columbia, Canada. It was established in 1974, and encompasses six large drainages in the Purcell Mountains in the southeast of the province. It contains high peaks, alpine meadows and ridges, deep creek and river valleys, and hot springs at Dewar Creek.
The Weminuche Wilderness is a wilderness area in southwest Colorado managed by the United States Forest Service as part of the San Juan National Forest on the west side of the Continental Divide and the Rio Grande National Forest on the east side of the divide. The Weminuche Wilderness was designated by Congress in 1975, and expanded by the Colorado Wilderness Acts of 1980 and 1993. It is located 4 miles (6.4 km) southeast of the town of Silverton, 17 miles (27 km) northeast of Durango, and 8 miles (13 km) west of South Fork. At 499,771 acres (2,022.50 km2), it is the largest wilderness area in the state of Colorado. Elevation in the wilderness ranges from 7,700 feet (2,300 m) along the Animas River to 14,093 feet (4,296 m) at the summit of Windom Peak.
Krummholz — also called knieholz — is a type of stunted, deformed vegetation encountered in the subarctic and subalpine tree line landscapes, shaped by continual exposure to fierce, freezing winds. Under these conditions, trees can only survive where they are sheltered by rock formations or snow cover. As the lower portion of these trees continues to grow, the coverage becomes extremely dense near the ground. In Newfoundland and Labrador, the formation is known as tuckamore. Krummholz trees are also found on beaches such as the Oregon coast, where trees can become much taller than their subalpine cousins.
The Tushar Mountains are the third highest mountain range in Utah after the Uinta Mountains and the La Sal Range. Located in the Fishlake National Forest, Delano Peak, 12,174 ft NAVD 88, is the highest point in both Beaver and Piute counties and has a prominence of 4,689 ft. Delano Peak is named for Columbus Delano (1809–1896), Secretary of the Interior during the Grant administration. The Tushars receive an ample amount of snow annually even though they are situated within the rainshadow of the Sierra Mountain Range located in California and the Snake Range located in Nevada.
Latir Peak Wilderness is a 20,506-acre (8,298 ha) wilderness area located within the Carson National Forest in northern New Mexico, United States. Designated in 1980, the wilderness is composed of dense forest, meadows, and alpine tundra on Latir Mesa in the northern portion. It includes a portion of the Sangre de Cristo Mountains and contains four of the state's twenty highest peaks - Venado Peak at 12,734 feet (3,881 m), Latir Peak at 12,708 feet (3,873 m), Latir Mesa at 12,692 feet (3,869 m), and Virsylvia Peak at 12,594 feet (3,839 m). Most of the area is drained by the Lake Fork of Cabresto Creek, which originates at Heart Lake and is impounded just outside the wilderness in Cabresto Lake, the main trailhead for visitors entering the wilderness.
Boulder River Wilderness is a 48,674-acre (197 km2) wilderness area within the Mount Baker-Snoqualmie National Forest in the western Cascade Range of Washington state.
The Ecology of the North Cascades is heavily influenced by the high elevation and rain shadow effects of the mountain range. The North Cascades is a section of the Cascade Range from the South Fork of the Snoqualmie River in Washington, United States, to the confluence of the Thompson and Fraser Rivers in British Columbia, Canada, where the range is officially called the Cascade Mountains but is usually referred to as the Canadian Cascades. The North Cascades Ecoregion is a Level III ecoregion in the Commission for Environmental Cooperation's classification system.
The Flat Tops is a mountain range located in Colorado within the Routt and White River National Forests. Much of the range is within the boundary of the Flat Tops Wilderness Area. While there are notable peaks in the Flat Tops, the dominant feature of the range is the high plateau from which the peaks arise. The plateau forms the northeastern portion of the White River Uplift capped by horizontal basalt flows from tertiary volcanic activity and is bounded by steep drops to valleys carved out by subsequent glaciation. The resulting mix of areas of treeless plateau at an elevation of 11,000 to 12,000 feet interspersed with verdant valleys is unique among Colorado mountain ranges. The area contains approximately one hundred and ten ponds and lakes and is home to a wide variety of plants and animals, including many large mammals such as moose, elk, mule deer, black bear, and cougars. This area has been affected by the non-native plant species, yellow toadflax. The most common trees are Engelmann spruce, subalpine fir and lodgepole pine, with aspen groves at lower elevations. The top of the plateau is alpine tundra.
The ecology of the Rocky Mountains is diverse due to the effects of a variety of environmental factors. The Rocky Mountains are the major mountain range in western North America, running from the far north of British Columbia in Canada to New Mexico in the southwestern United States, climbing from the Great Plains at or below 1,800 feet (550 m) to peaks of over 14,000 feet (4,300 m). Temperature and rainfall varies greatly also and thus the Rockies are home to a mixture of habitats including the alpine, subalpine and boreal habitats of the Northern Rocky Mountains in British Columbia and Alberta, the coniferous forests of Montana and Idaho, the wetlands and prairie where the Rockies meet the plains, a different mix of conifers on the Yellowstone Plateau in Wyoming and in the high Rockies of Colorado and New Mexico, and finally the alpine tundra of the highest elevations.
The Hermosa Creek Wilderness is a 37,236-acre (15,069 ha) U.S. Wilderness Area in La Plata County, Colorado. It s located in the San Juan National Forest 12 miles (19 km) north of Durango. It was established by the Hermosa Creek Protection Act of 2014, which also created the adjacent Hermosa Creek Special Management Area, which shares its eastern border, Hermosa Creek. Elevation in the wilderness ranges from 7,500 feet (2,300 m) along Hermosa Creek to 12,338 feet (3,761 m) at the high point of Indian Trail Ridge.
