Physiography (land forms)

USGS shaded relief map of South Dakota

South Dakota is divided into three separate regions. The main division is demarcated by the Missouri River which flows through the center of the state from north to south dividing the state into an eastern and a western region.

The eastern poriton of the state was formed by glacial deposition and is generally flat with a very slight rise as one travels from east to west.

West of the Missouri, the land continues to rise, but at a slightly steeper rate, from about 2000 feet above sea level at the Missouri River to over 3000 feet in elevation in the extreme northwest part of the state. This region is part of the Great Plains.

The third distinct region is the Black Hills area in the southwestern part of the state. This is a mountainous region, covered by a pine forest, and was sacred to the native peoples of the Great Plains.

Climate

Governing the climate in South Dakota is the fact that the state does not lie close to any large bodies of water and thus does not experience the moderating influence of such formations on overall weather patterns. As a result, South Dakota experiences hot summers and cold winters with larger than normal seasonal and diurnal fluctuations in temperature.

During the peak summer months, mean daily maximum temperatures will be in the mid to upper 80s (degrees F) while during the winter months mean daily lows will be in the teens or single digits (degrees F).

Annual precipitation averges range from 25 inches plus in the southeast portion of the state, decreasing gradually as one goes across the state from the east to the semi-arid west where the average annual preciiptation will be less than 17 inches.

The current governor of the state, M. Michael Rounds, a Republican from Pierre, is in his second term of office, having been elected to the post in 2002 and re-elected in 2006.

The state legislature is elected from 35 districts, each of which elects 2 members to the state House of Representatives and 1 member to the State Senate.
