Monson Lake State Park
Monson Lake State Park is a state park of Minnesota, USA, originally established as a memorial to 13 Swedish American pioneers who were killed there in the Dakota War of 1862. A district of 1930s New Deal structures is on the National Register of Historic Places. Despite being nearly doubled in size in 2009, the state park remains one of Minnesota's smallest. It is located off Minnesota State Highway 9 just west of Sunburg and northwest of Willmar. This seasonally-staffed park is managed from nearby Sibley State Park. Geography Much of Monson Lake State Park's acreage is water, with land mostly comprising isthmuses between, and islands in, the three adjacent lakes of Monson, West Sunburg, and East Sunburg. Monson Lake, whose shore forms the western boundary of the park, is and up to deep. West Sunburg Lake is about . Monson Lake has three inlets, and one outlet to West Sunburg. The lakes are part of the watershed of the Chippewa River, a tributary of the Minnesota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swift County, Minnesota
Swift County is a county in the U.S. state of Minnesota. As of the 2020 census, the population was 9,838. Its county seat is Benson. History Swift County is in west central Minnesota and consists of with three tiers of seven townships each. It was established on February 18, 1870, and named for Henry Adoniram Swift, the third governor of Minnesota (1863–64). The Indians had grievances against the government, including delays in sending annuities that caused near starvation several times. In August 1862, an Indian rebellion broke out in Minnesota. The warfare reached the settlements just getting started in northeastern Swift County. By late September 1862, the Indian War was almost over but the settlers hesitated to venture back to Swift County until 1865, when all danger was apparently over. Scandinavians and Germans were in decided majority among the early settlers. A number of them came with the honor and privileges of Civil War veterans. In 1869, the St. Paul & Pacifi ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

Understory
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...

Carpinus Caroliniana
''Carpinus caroliniana'', the American hornbeam, is a small hardwood tree in the genus ''Carpinus''. American hornbeam is also known as blue-beech, ironwood, musclewood and muscle beech. It is native to eastern North America, from Minnesota and southern Ontario east to Maine, and south to eastern Texas and northern Florida. It also grows in Canada (southwest Quebec and southeast Ontario). It occurs naturally in shaded areas with moist soil, particularly near the banks of streams or rivers, and is often a natural constituent understory species of the riverine and maritime forests of eastern temperate North America. Description American hornbeam is a small tree reaching heights of , rarely , and often has a fluted and crooked trunk. The bark is smooth and greenish-grey, becoming shallowly fissured in all old trees. The leaves are alternate, long, with prominent veins giving a distinctive corrugated texture, and a serrated margin. The male and female catkins appear in spring at t ...

Quercus Rubra
''Quercus rubra'', the northern red oak, is an oak tree in the red oak group (''Quercus'' section ''Lobatae''). It is a native of North America, in the eastern and central United States and southeast and south-central Canada. It has been introduced to small areas in Western Europe, where it can frequently be seen cultivated in gardens and parks. It prefers good soil that is slightly acidic. Often simply called red oak, northern red oak is so named to distinguish it from southern red oak (''Q. falcata''), also known as the Spanish oak. Northern Red Oak is sometimes called champion oak. Description In many forests, this deciduous tree grows straight and tall, to , exceptionally to tall, with a trunk of up to in diameter. Open-grown trees do not get as tall, but can develop a stouter trunk, up to in diameter. It has stout branches growing at right angles to the stem, forming a narrow round-topped head. Under optimal conditions and full sun, northern red oak is fast growing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fraxinus Pennsylvanica
''Fraxinus pennsylvanica'', the green ash or red ash, is a species of ash native to eastern and central North America, from Nova Scotia west to southeastern Alberta and eastern Colorado, south to northern Florida, and southwest to Oklahoma and eastern Texas. It has spread and become naturalized in much of the western United States and also in Europe from Spain to Russia. Other names more rarely used include downy ash, swamp ash and water ash. Description ''Fraxinus pennsylvanica'' is a medium-sized deciduous tree reaching (rarely to ) tall with a trunk up to in diameter. The bark is smooth and gray on young trees, becoming thick and fissured with age. The winter buds are reddish-brown, with a velvety texture. The leaves are long, oppositely arranged, pinnately compound with seven to nine (occasionally five or eleven) leaflets, these (rarely ) long and broad, with serrated margins and short but distinct, downy petiolules a few millimeters long. They are green both above ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Macrocarpa
''Quercus macrocarpa'', the bur oak or burr oak, is a species of oak tree native to eastern North America. It is in the white oak section, ''Quercus'' sect. ''Quercus'', and is also called mossycup oak, mossycup white oak, blue oak, or scrub oak. The acorns are the largest of any North American oak (thus the species name ''macrocarpa'', from Ancient Greek "large" and "fruit"), and are important food for wildlife. Description ''Quercus macrocarpa'' is a large deciduous tree growing up to , rarely , in height, and is one of the most massive oaks with a trunk diameter of up to ; reports of taller trees occur, but have not been verified. It is one of the slowest-growing oaks, with a growth rate of per year when young. However, one source states that a well-established tree can grow up to per year. A 20-year-old tree will be about tall if grown in full sun. Naturally occurring saplings in forests will typically be older. Bur oaks commonly get to be 200 to 300 years old, and ma ...

Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable 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 fire, prairie fire, vegetation fire, or veld fire. Fire ecology, Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burn, controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurre ...

Tallgrass Prairie
The tallgrass prairie is an ecosystem native to central North America. Historically, natural and anthropogenic fire, as well as grazing by large mammals (primarily bison) provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination. Prior to widespread use of the steel plow, which enabled large scale conversion to agricultural land use, tallgrass prairies extended throughout the American Midwest and smaller portions of southern central Canada, from the transitional ecotones out of eastern North American forests, west to a climatic threshold based on precipitation and soils, to the southern reaches of the Flint Hills in Oklahoma, to a transition into forest in Manitoba. They were characteristically found in the central forest-grasslands transition, the central tall grasslands, the upper Midwest forest-savanna transition, and the northern tall grasslands ecoregions. They flouris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kettle (landform)
A kettle (also known as a kettle lake, kettle hole, or pothole) is a depression/hole in an outwash plain formed by retreating glaciers or draining floodwaters. The kettles are formed as a result of blocks of dead ice left behind by retreating glaciers, which become surrounded by sediment deposited by meltwater streams as there is increased friction. The ice becomes buried in the sediment and when the ice melts, a depression is left called a kettle hole, creating a dimpled appearance on the outwash plain. Lakes often fill these kettles; these are called kettle hole lakes. Another source is the sudden drainage of an ice-dammed lake. When the block melts, the hole it leaves behind is a kettle. As the ice melts, ramparts can form around the edge of the kettle hole. The lakes that fill these holes are seldom more than deep and eventually fill with sediment. In acid conditions, a kettle bog may form but in alkaline conditions, it will be kettle peatland. Overview Kettles are fluviog ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.
