context_page_description: South Dakota is a state located in the north-central United States. It is usually considered to be in the Midwestern region of the country. The state can generally be divided into three geographic regions: eastern South Dakota, western South Dakota, and the Black Hills. Eastern South Dakota is lower in elevation and higher in precipitation than the western part of the state, and the Black Hills are a low, isolated mountain group in the southwestern corner of the state. Smaller sub-regions in the state include the Coteau des Prairies, Coteau du Missouri, James River Valley, the Dissected Till Plains. Geologic formations in South Dakota range in age from two billion-year-old Precambrian granite in the Black Hills to glacial till deposited over the last few million years. South Dakota is the 17th-largest state in the country.
  South Dakota has a humid continental climate in the east and in the Black Hills, and a semi-arid climate in the west outside of the Black Hills, featuring four very distinct seasons, and the ecology of the state features plant and animal species typical of a North American temperate grassland biome.
context_section_description: South Dakota's early economy relied heavily on the soil, minerals and ecology of the area, as nearly all of the earliest white settlers in the area were farmers, miners, or trappers. Although other economic sectors have risen in prominence in recent years, early dependence on the land laid the foundation for the future economic activity of the state.
  Agriculture has historically been a key component of the South Dakota economy. Although other industries have expanded rapidly in recent decades, agricultural production is still very important to the state's economy, especially in rural areas. The five most valuable agricultural products in South Dakota are cattle, corn (maize), soybeans, wheat, and hogs. Agriculture-related industries such as meat packing and ethanol production also have a considerable economic impact on the state. South Dakota is one of the largest producers of ethanol in the nation.
  Another important sector in South Dakota's economy is tourism. Many travel to visit the national parks, state parks, and national monuments in the state, particularly those of the Black Hills region. South Dakota's location between national parks in the west and large cities to the east also contributes to the state's tourism and hospitality industry. In 2006, tourism provided an estimated 33,000 jobs in the state and contributed over two billion US$ to the economy of South Dakota.
