One of the world's largest freshwater lakebed oolites is the Shoofly Oolit, a section of the Glenns Ferry Formation on southwestern Idaho's Snake River Plain. The material consolidated and eroded during later exposure above the ocean surface. This limestone was formed by deposition when shallow seas covered the area between periods of glaciation. The Atlantic Coastal Ridge of southeastern Florida, the islands of the Lower Florida Keys, and much of the Everglades, are underlain by Miami Oolite. Carboniferous Hunts Bay Oolite lies under much of south Wales. A particular type, Bath Stone, gives the buildings of the World Heritage City of Bath their distinctive appearance. Some exemplar oolitic limestone was formed in England during the Jurassic period, and forms the Cotswold Hills, the Isle of Portland with its famous Portland Stone, and part of the North York Moors. Because of its extremely small grain size, oolitic sand has a lot of surface area, which promotes high bacterial growth. Importantly, this unusually smooth sand promotes the growth of bacteria, which are important biofilters in home aquaria. Also known as "oolitic" sand, the sugar-sized round grains of this sand pass easily through the gills of gobies and other sand-sifting organisms. Oolites are often used in the home aquarium industry because their small grain size (0.2 to 1.22 mm) is ideal for shallow static beds and bottom covering of up to 1" in depth. The size of the oolites reflect the time that they were exposed to the water before they were covered with later sediment. The oolites are commonly found in large current bedding structures that resemble sand dunes. Strong intertidal currents wash the 'seeds' around on the seabed, where they accumulate layers of chemically precipitated calcite from the supersaturated water. The mechanism of formation starts with a small fragment of sediment acting as a 'seed', e.g., a piece of a shell. They are usually formed in warm, supersaturated, shallow, highly agitated marine water intertidal environments, though some are formed in inland lakes. Oolitic hematite occurs at Red Mountain near Birmingham, Alabama, along with oolitic limestone. Dolomitic and chert ooids are most likely the result of the replacement of the original texture in limestone. The state capital and largest city is Boise.Ooids are most commonly composed of calcium carbonate ( calcite or aragonite), but can be composed of phosphate, clays, chert, dolomite or iron minerals, including hematite. The state population was about 1.58M in July 2011 with 84% being Caucasian, 11.2% Hispanic and 1.1% Native American. Idaho is very mountainous and is a popular outing destination of the outdoorsman. There is a possibility it was derived from a Native American phrase. There is some ambiguity as to where the name "Idaho" came from, but it is generally believed to have simply been made up by George M. Idaho also hosts the largest barrel cheese factory in the world, producing 120K metric tons of cheese per year. Idaho is also famous for producing about one third of all potatoes grown in the USA. Idaho is nicknamed "The Gem State" because nearly every known gemstone is found within the state. Idaho is landlocked, being bordered by Canada on the north and the states of Washington and Oregon on the west, Nevada and Utah on the south and Montana and Wyoming on the east. Idaho was the 43rd state to be admitted into the Union, on July 3, 1890. Idaho is the 14th largest state by area, ranks 39th by population and 53rd by population density of the 50 United States. Idaho is a state located in the northwestern region of the United States of America.
