A bill for statehood for North and South Dakota (and Montana, and Washington) was passed on February 22 1889 during the Administration of Grover Cleveland. It was left to his successor Benjamin Harrison to sign proclamations formally admitting North and South Dakota to the Union on November 2 1889. However, the rivalry between the northern and southern territories presented a dilemma: only one, upon the President's signature on the proclamation, could gain the distinction of being admitted before the other. So Harrison directed his Secretary of State James Blaine to shuffle the papers and obscure from him which he was signing first, and the priority went unrecorded.
South Dakota license plates are numbered by county, with the first digit referring to the county of origin. Such a numbering system allows one to easily determine where the vehicle was registered. Counties 1-10 are ranked, roughly, by population. 11-67 are numbered alphabetically.

The deepest mine in the United States, the Homestake gold mine (now defunct), is in the Black Hills of South Dakota, near the town of Lead. Its shaft plunges more than 8,000 feet beneath the surface. From 1969 until 1993, it was home to the Homestake Chlorine Solar Neutrino Experiment, famous for detecting the solar neutrino problem. Currently there is pending legislation that would give the mine to the National Science Foundation for use as an underground research laboratory.
