Missouri River Valley
The Missouri River Valley outlines the journey of the Missouri River from its headwaters where the Madison, Jefferson and Gallatin Rivers flow together in Montana to its confluence with the Mississippi River in the State of Missouri. At long the valley drains one-sixth of the United States, and is the longest river valley on the North American continent. The valley in the Missouri River basin includes river bottoms and floodplains. Geography The Missouri's valley ranges from to wide from edge to edge, with gentle slopes from the adjacent upland to the valley floor. Other segments are narrow, less than two miles (3 km) wide, with rugged valley sides. Generally, the wide segments trend west-east and the narrow segments trend north-south. Starting in the state of Montana, the Missouri River Valley travels through North Dakota, South Dakota, forms the shared border of eastern Nebraska and western Iowa, goes into Kansas and then eastward through the state of Missouri.

Rulo, Nebraska
Rulo is a village in Richardson County, Nebraska, United States. The population was 144 at the 2020 census. History Rulo was laid out in 1857.

Brownville, Nebraska
Brownville is a village in Nemaha County, Nebraska, United States. The population was 142 at the 2020 census. History Established in 1854 and incorporated in 1856, Brownville was the largest town in the Nebraska Territory, with a population of 1,309 by 1880. Bordering slave-holding Missouri, the town became an important port on the Missouri River. Daniel Freeman, the first homesteader to file a claim under the Homestead Act of 1862, staked his claim at a New Year's Eve party in Brownville. The rise of the railroad was ultimately Brownville's undoing. The railroads siphoned traffic away from the Missouri River's steamboats. Brownville's attempt to secure a railroad of its own was severely botched and led to immense tax increases to pay the bonds for the failed venture. This drove most of the population away and led to the county seat being transferred to Auburn in 1885. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loess
Loess (, ; from german: Löss ) is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. Ten percent of Earth's land area is covered by loess or similar deposits. Loess is a periglacial or aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay and a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers), often loosely cemented by calcium carbonate. It is usually homogeneous and highly porous and is traversed by vertical capillaries that permit the sediment to fracture and form vertical bluffs. Properties Loess is homogeneous, porous, friable, pale yellow or buff, slightly coherent, typically non- stratified and often calcareous. Loess grains are angular, with little polishing or rounding, and composed of crystals of quartz, feldspar, mica and other minerals. Loess can be described as a rich, dust-like soil. Loess deposits may become very thick, more than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
