The state was named for the Colorado River, which Spanish travelers named the Río Colorado for the ruddy (Spanish: colorado) silt the river carried from the mountains. The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulysses S. Grant signed Proclamation 230 admitting Colorado to the Union as the 38th state. Colorado is nicknamed the "Centennial State" because it became a state a century after the signing of the United States Declaration of Independence.
Minnesota is the 12th largest in area and the 21st most populous of the U.S. states; nearly 60 percent of its residents live in the Minneapolis–Saint Paul metropolitan area (known as the "Twin Cities"), the center of transportation, business, industry, education, and government and home to an internationally known arts community. The remainder of the state consists of western prairies now given over to intensive agriculture; deciduous forests in the southeast, now partially cleared, farmed and settled; and the less populated North Woods, used for mining, forestry, and recreation.
