Michigan Basin. Coordinates: 43°40′N 84°45′W. Geologic map of the Michigan Basin. The Michigan Basin is a geologic basin centered on the Lower Peninsula of the U.S. state of Michigan. The feature is represented by a nearly circular pattern of geologic sedimentary strata in the area with a nearly uniform structural dip toward the center of ...
At a total area of 97,990 square miles (253,800 km 2) – including those territorial waters – Michigan is the largest state east of the Mississippi River, and the eleventh largest state overall. More than half of the state's land area – 30,156 square miles (78,100 km 2) – is still forest. The state lies roughly between 41° and 49 ...
The lake is about 6 miles (9.7 km) long with a maximum width of 1.2 miles (1.9 km) and a surface area of 1,700 acres (2.7 sq mi; 6.9 km 2).The average depth of the lake is variable but generally less than 10 feet (3 m), excluding a navigation channel of fixed depth that crosses the lake to allow deep draft ships to access the dock at the City of Holland.
Kalkaska sand is the official soil of the U.S. state of Michigan. Kalkaska sand was identified in 1927 and named after Kalkaska County located in the northern Lower Peninsula of Michigan. This soil is a multi-layer soil composed of humus, light sand, dark sand, and yellowish sand. It is classified as a spodosol. The distinctive sand layers can ...
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt): If the ...
Lake Michigan–Huron (also Huron–Michigan) is the body of water combining Lake Michigan and Lake Huron, which are joined through the 5-mile-wide (8.0 km), 295- foot -deep (90 m), open-water Straits of Mackinac. Huron and Michigan are hydrologically a single lake because the flow of water through the straits keeps their water levels in ...
Topsoil is composed of mineral particles and organic matter and usually extends to a depth of 5-10 inches (13–25 cm). Together these make a substrate capable of holding water and air which encourages biological activity. There are generally a high concentration of roots in topsoil since this is where plants obtain most of their vital nutrients.
Following is a list of dams and reservoirs in Michigan. Major dams are linked below. The National Inventory of Dams defines any "major dam" as being 50 feet (15 m) tall with a storage capacity of at least 5,000 acre-feet (6,200,000 m 3 ), or of any height with a storage capacity of 25,000 acre-feet (31,000,000 m 3 ).
