List Of National Natural Landmarks
The National Natural Landmarks (NNL) Program recognizes and encourages the conservation of outstanding examples of the natural history of the United States. It is the only national natural areas program that identifies and recognizes the best examples of biological and geological features in both public and private ownership. The program was established on May 18, 1962, by United States Secretary of the Interior Stewart Udall. The program aims to encourage and support voluntary preservation of sites that illustrate the geological and ecological history of the United States. It also hopes to strengthen the public's appreciation of the country's natural heritage. As of January 2021, 602 sites have been added to the National Registry of Natural Landmarks. The registry includes nationally significant geological and ecological features in 48 states, American Samoa, Guam, Puerto Rico, and the U.S. Virgin Islands. The National Park Service administers the NNL Program and if reques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hayden Prairie State Preserve
The Hayden Prairie State Preserve is a tallgrass prairie located in Howard County, Iowa. It is a National Natural Landmark managed by the Iowa Department of Natural Resources. Located close to the northern border of the state of Iowa, the nearest towns are Chester and Lime Springs. History The prairie commemorates botanist Ada Hayden (1884–1950). An Iowa farm girl, Hayden studied at the Missouri Botanical Garden (MBG) and Iowa State University (ISU) and earned a PhD in biology in 1918, one of the first women to earn this distinction in the U.S. She became an assistant professor of botany at ISU, devoting her personal and professional life to the defense of the fast-disappearing tallgrass prairies of her native state. During her working lifetime, most of the remaining patches of tallgrass that had survived the rush of Euro-American settlement in the 1800s were falling to the plowshare. Finally in 1940, the state of Iowa allocated $100 to Hayden for gasoline to drive arou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern White Pine
''Pinus strobus'', commonly called the eastern white pine, northern white pine, white pine, Weymouth pine (British), and soft pine is a large pine native to eastern North America. It occurs from Newfoundland, Canada west through the Great Lakes region to southeastern Manitoba and Minnesota, United States, and south along the Appalachian Mountains and upper Piedmont to northernmost Georgia and perhaps very rarely in some of the higher elevations in northeastern Alabama. It is considered rare in Indiana. The Native American Haudenosaunee named it the "Tree of Peace". It is known as the "Weymouth pine" in the United Kingdom, after Captain George Weymouth of the British Royal Navy, who brought its seeds to England from Maine in 1605. Distribution ''P. strobus'' is found in the nearctic temperate broadleaf and mixed forests biome of eastern North America. It prefers well-drained or sandy soils and humid climates, but can also grow in boggy areas and rocky highlands. In mixed f ...

Dubuque County, Iowa
Dubuque County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 99,266, making it the eighth-most populous county in Iowa. The county seat is Dubuque. The county is named for Julien Dubuque, the first European settler of Iowa. Dubuque County comprises the Dubuque, IA Metropolitan Statistical Area. History Early history Dubuque County is named for French trader Julien Dubuque, the first European settler of Iowa, and an early lead mining pioneer in what is now Dubuque County. Dubuque was French Canadian, and had (by most accounts) a friendly relationship with the local Fox tribe of Native Americans. He and other early pioneers established a lucrative mining and trading industry in the area. When lead deposits began becoming exhausted, the pioneers developed boat building, lumber yards, milling, brewing, and machinery manufacturing to take its place. The city of Dubuque was chartered in 1833 as the first city in Iowa. The establishment of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Pine Hollow State Forest
The White Pine Hollow State Forest is a forested area in Dubuque County, Iowa. Of the forest, a tract is a National Natural Landmark and Iowa State Preserve. The state forest is named after its dominant old-growth tree, the white pine. The grove is said to be the only old-growth patch of white pines still growing in Iowa. The nearest town of any size is Luxemburg. Formerly known as: "Pine Creek Hollow," and "Pine Hollow". Ecology The Dubuque region is relatively far south for the white pine to thrive. White Pine Hollow, part of the Driftless Area, is a patch of north-facing algific talus slope land, a subset of dolomite karstland with many sinkholes, caverns, and other sharp changes in elevation. The conifer population may have established itself here at a time when the climate of Iowa was colder than it is today, and this grove could be a relict of what was once a much larger population. White Pine Hollow contains over 625 species of plants. Two endangered species of ... [...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] |
Monona County, Iowa

Many years later, that site was memorialized as the Lewis and Clark State Park. Monona County was formed in 1851. It was perhaps named for an Indian word meaning "beautiful valley." Monona County was organized officially in the spring of 1854 having been a part of Benton County (every county west of Benton in a line) in 1851 and afterwards Harrison County between 1852 and 1854. When Ashton (originally called Bloomfield) was named the county seat in the fall of 1854, a log house served as the first courthouse. Ashton remained the county seat for only four years. That designation was moved to Onawa on April 5, 1858, and the first Monona County Courthouse was compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
