Saint Mary Peak
Saint Mary Peak is a mountain summit located in Ravalli County, Montana. Description Saint Mary Peak is located in the Bitterroot Range, which is a subset of the Rocky Mountains. It is situated eight miles west of Stevensville in the Selway–Bitterroot Wilderness, on land managed by Bitterroot National Forest. The summit lies five miles east of the Idaho–Montana border. Precipitation runoff from the mountain drains into tributaries of the Bitterroot River. Topographic relief is significant as the summit rises over above Big Creek in three miles. A popular 3.5-mile hiking trail leads to a fire lookout tower at the summit.Aaron Theisen (2018), ''Day Hiking: Glacier National Park and Western Montana'', Mountaineers Books, The lookout was originally built in 1931 and reconstructed in 1953, and was placed on the National Register of Historic Places in 2018. This landform's toponym has been officially adopted by the United States Board on Geographic Names. Climate Base ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ravalli County, Montana
Ravalli County is a county in the southwestern part of the U.S. state of Montana. As of the 2020 census, the population was 44,174. Its county seat is Hamilton. Ravalli County is part of a north–south mountain valley bordered by the Sapphire Mountains on the East and the Bitterroot Mountains on the West. It is often referred to as the Bitterroot Valley, which is named for the Bitterroot Flower. The county is on the Pacific Ocean side of the Continental Divide, which follows the Idaho-Montana border from Wyoming until Ravalli County. Here, it turns east into Montana, between Chief Joseph Pass and Lost Trail Pass, and follows the Ravalli County-Beaverhead County border. History Ravalli County was once home to the Bitterroot Salish tribe. The tribe was first encountered in 1805 by the Lewis and Clark Expedition, which noted their friendly nature. The Catholic Church took an interest in creating a mission in the area, and in 1841 founded St. Mary's Mission, subsequently rena ...

National Register Of Historic Places
The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property. The passage of the National Historic Preservation Act (NHPA) in 1966 established the National Register and the process for adding properties to it. Of the more than one and a half million properties on the National Register, 95,000 are listed individually. The remainder are contributing resources within historic districts. For most of its history, the National Register has been administered by the National Park Service (NPS), an agency within the U.S. Department of the Interior. Its goals are to help property owners and inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Ravalli County, Montana
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain a ...

Geology Of The Rocky Mountains
The geology of the Rocky Mountains is that of a discontinuous series of mountain ranges with distinct geological origins. Collectively these make up the Rocky Mountains, a mountain system that stretches from Northern British Columbia through central New Mexico and which is part of the great mountain system known as the North American Cordillera. The rocky cores of the mountain ranges are, in most places, formed of pieces of continental crust that are over one billion years old. In the south, an older mountain range was formed 300 million years ago, then eroded away. The rocks of that older range were reformed into the Rocky Mountains. The Rocky Mountains took shape during an intense period of plate tectonic activity that resulted in much of the rugged landscape of the western North America. The Laramide orogeny, about 80–55 million years ago, was the last of the three episodes and was responsible for raising the Rocky Mountains. Subsequent erosion by glaciers has created the ...

Heavenly Twins (Montana)
Heavenly Twins is a double summit mountain located in Ravalli County, Montana. Description Heavenly Twins is located in the Bitterroot Range, which is a subset of the Rocky Mountains. It is situated 11 miles west of Stevensville in the Selway–Bitterroot Wilderness, on land managed by Bitterroot National Forest. The summit lies 2.5 miles east of the Continental Divide and the Idaho–Montana border. The true summit is the south peak which is one-third mile from the 9,243-ft north peak, and the nearest higher neighbor is line parent Saint Mary Peak three miles to the east. Precipitation runoff from the mountain drains into tributaries of the Bitterroot River. Topographic relief is significant as the summit rises above Big Creek in two miles. This landform's toponym has been officially adopted by the United States Board on Geographic Names. The name refers to Castor and Pollux, also called the heavenly twins.

Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50° to 70°N, poleward of the humid continental climates. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least one month) must have a 24-hour average temperature of at least to fall into this category of climate, and the coldest month should ave ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geographic names throughout the federal government of the United States. History On January 8, 1890, Thomas Corwin Mendenhall, superintendent of the US Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography." President Benjamin Harrison signed executive order 28 on September 4, 1890, establishing the ''Board on Geographical Names''. "To this Board shall be referred all unsettled questions concerning geographic names. The decisions of the Board are to be accepted y federal departmentsas the standard authority for such matters." The board was given authority to resolve all unsettled ques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Lookout Tower
A fire lookout tower, fire tower or lookout tower, provides housing and protection for a person known as a "fire lookout" whose duty it is to search for wildfires in the wilderness. It is a small building, usually on the summit of a mountain or other high vantage point, to maximize viewing distance and range, known as ''view shed''. From this vantage point the fire lookout can see smoke that may develop, determine the location by using a device known as an ''Osborne Fire Finder'', and call fire suppression personnel to the fire. Lookouts also report weather changes and plot the location of lightning strikes during storms. The location of the strike is monitored for a period of days afterwards, in case of ignition. A typical fire lookout tower consists of a small room, known as a ''cab,'' atop a large steel or wooden tower. Historically, the tops of tall trees have also been used to mount permanent platforms. Sometimes natural rock may be used to create a lower platform. In cases ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/ British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. The ...
