Snake River Birds Of Prey National Conservation Area
The Morley Nelson Snake River Birds of Prey National Conservation Area has one of the densest populations of nesting raptors. The National Conservation Area (NCA) is located south of Boise, Idaho along of the Snake River, and is managed by the Bureau of Land Management. The NCA covers . In descending order of land area it is located in Ada, Elmore, Owyhee, and Canyon counties. Section 2301 of the Omnibus Public Lands Management Act of 2009, section 2301 renamed the area as the Morley Nelson Snake River Birds of Prey National Conservation Area in recognition of the contributions of Morley Nelson, a raptor expert and advocate and a leading proponent of the original creation of the National Conservation Area. About 14,000 years ago, as glaciers receded from the last ice age, the Lake Bonneville crested at Red Rock Pass, Idaho, creating what is known as the Bonneville Flood. As soft soils eroded at the pass, the lake poured into the volcanic plain of the Snake River and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prairie Falcon
The prairie falcon (''Falco mexicanus'') is a medium-sized Falconiformes, falcon found in Western North America. A separate species from the peregrine falcon, with which it shares some visual similarities, the prairie falcon is, essentially, an arid-climate divergence of earlier peregrine falcon lineage. It is thus able to thrive on a more meager, opportunistic diet compared to that of the peregrine, and is generally lighter in weight than a peregrine of similar wingspan. Having evolved in harsher and desert environments, often with low prey density, the prairie falcon has developed into an aggressive and opportunistic hunter of a wide range of both mammalian and avian prey, as well as occasional reptiles. It will regularly take prey from the size of House sparrow, sparrows or Finch, finches to birds approximately its own weight, and occasionally much larger. The prairie falcon is the only larger falcon species native strictly to North America (others are found throughout the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonneville Flood
The Bonneville flood was a catastrophic flooding event in the last ice age, which involved massive amounts of water inundating parts of southern Idaho and eastern Washington along the course of the Snake River. Unlike the Missoula Floods, which also occurred during the same period in the Pacific Northwest, the Bonneville flood happened only once. Cause and events About 14,500 years ago (radiocarbon dating, 17,400 years ago calendar, "calibrated" dating), pluvial Lake Bonneville in northern Utah reached its highest water level since its formation. The lake occupied the present-day basin of the Great Salt Lake, and was far larger, covering about . As it rose the lake level caused seepage at, then breached, the ancient level of Red Rock Pass, a mountain pass at the headwaters of the Portneuf River, a tributary of the Snake River above present-day American Falls Reservoir. Ancient Red Rock Pass was the site of two alluvial fans descending from opposite sides of the notch, form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pit Crater
A pit crater (also called a subsidence crater or collapse crater) is a depression formed by the sinking or collapse of the surface lying above a void or empty chamber, rather than by the eruption of a volcano or lava vent. Pit craters are found on Mercury, Venus, Earth, Mars, and the Moon. Pit craters are often found in a series of aligned or offset chains; in these cases, the features is called a ''pit-crater chain''. Pit-crater chains are distinguished from catenae or crater chains by their origin. When adjoining walls between pits in a pit-crater chain collapse, they become troughs. In these cases, the craters may merge into a linear alignment and are commonly found along extensional structures such as fractures, fissures, and graben. Pit craters usually lack an elevated rim as well as the ejecta deposits and lava flows that are associated with impact craters.Okubo, Chris, and Stephen Martel.

Crater Rings (Idaho)
Crater Rings are adjacent, symmetrical volcanic pit craters in the Western Snake River Plain about eight miles northwest of Mountain Home, Idaho. They are one of few examples of volcanic craters in the continental United States. The craters are at the summit of a broad shield volcano. The eastern crater is about 3000 ft across and 350 ft deep. The western is 2500 ft across and 300 ft deep. The craters are probably former lava lakes similar to Halemaʻumaʻu of the Kīlauea volcano of Hawaii. The volcano is the youngest of the shield volcanoes near Mountain Home and is estimated to be less than two million years old. Crater Rings are a National Natural Landmark designated in 1980. The site is owned by the Bureau of Land Management as part of the Morley Nelson Snake River Birds of Prey National Conservation Area.

Military
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstruct ...

Wildfire
A wildfire, forest fire, or a bushfire is an unplanned and uncontrolled fire in an area of Combustibility and flammability, combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire (Bushfires in Australia, in Australia), desert fire, grass fire, hill fire, Peat#Peat fires, peat fire, prairie fire, vegetation fire, or veld fire. Some natural forest ecosystems Fire ecology, depend on wildfire. Modern forest management often engages in prescribed burns to mitigate fire risk and promote natural forest cycles. However, controlled burns can turn into wildfires by mistake. Wildfires can be classified by cause of ignition, physical properties, combustible material present, and the effect of weather on the fire. Wildfire severity results from a combination of factors such as available fuels, physical setting, and weather. Climatic cycles with wet periods that create substantial fuels, followed by drought and heat, of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Badger
Badgers are medium-sized short-legged omnivores in the superfamily Musteloidea. Badgers are a polyphyletic rather than a natural taxonomic grouping, being united by their squat bodies and adaptions for fossorial activity rather than by their ancestral relationships: Musteloidea contains several families, only two of which (the "weasel family" Mustelidae and the "skunk family" Mephitidae) include badgers; moreover, both of these families also include various other animals that are not badgers. The fifteen species of mustelid badgers are grouped in four subfamilies: four species of Melinae (genera ''Meles'' and ''Arctonyx'') including the European badger, five species of Helictidinae (genus ''Melogale'') or ferret-badger, the honey badger or ratel Mellivorinae (genus ''Mellivora''), and the American badger Taxideinae (genus ''Taxidea''). Badgers include the most basal mustelids; the American badger is the most basal of all, followed successively by the ratel and the Mel ...

Jackrabbit
Hares and jackrabbits are mammals belonging to the genus ''Lepus''. They are herbivores and live solitarily or in pairs. They nest in slight depressions called forms, and their young are able to fend for themselves shortly after birth. The genus includes the largest lagomorphs. Most are fast runners with long, powerful hind legs, and large ears that dissipate body heat. Hare species are native to Africa, Eurasia and North America. A hare less than one year old is called a "leveret". Members of the ''Lepus'' genus are considered true hares, distinguishing them from rabbits which make up the rest of the Leporidae family. However, there are five leporid species with "hare" in their common names which are not considered true hares: the hispid hare (''Caprolagus hispidus''), and four species known as red rock hares (''Pronolagus''). Conversely, several ''Lepus'' species are called "jackrabbits", but classed as hares rather than rabbits. The pet known as the Belgian hare is a dome ...

Paiute Ground Squirrel
Paiute (; also Piute) refers to three non-contiguous groups of Indigenous peoples of the Great Basin. Although their languages are related within the Numic group of Uto-Aztecan languages, these three languages do not form a single subgroup and they are no more closely related to each than they are to the Central Numic languages (Timbisha, Shoshoni, and Comanche) which are spoken between them. The term "Paiute" does not refer to a single, unique, unified group of Great Basin tribes, but is a historical label comprising: * Northern Paiute people of northeastern California, northwestern Nevada, eastern Oregon, and southern Idaho * Southern Paiute people of northern Arizona, southern Nevada, and southwestern Utah * Mono people of east central California, divided into Owens Valley Paiute (Eastern Mono) and Western Mono The Mono ( ) are a Native American people who traditionally live in the central Sierra Nevada, the Eastern Sierra (generally south of Bridgeport), the Mono Basi ...

Mammal
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Vegetation
Vegetation is an assemblage of plants and the ground cover they provide. It is a general term, without specific reference to particular Taxon, taxa, life forms, structure, Spatial ecology, spatial extent, or any other specific Botany, botanical or geographic characteristics. It is broader than the term ''Flora (plants), flora'' which refers to species richness, species composition. Perhaps the closest synonym is ''plant community'', but "vegetation" can, and often does, refer to a wider range of spatial scales than that term does, including scales as large as the global. Primeval redwood forests, coastal mangrove stands, sphagnum bogs, desert soil crusts, Road verge, roadside weed patches, wheat fields, cultivated gardens and lawns; all are encompassed by the term "vegetation". The vegetation type is defined by characteristic dominant species, or a common aspect of the assemblage, such as an elevation range or environmental commonality.
