As specified in the designating legislation for the Territory of Wyoming, Wyoming's borders are lines of latitude, 41°N and 45°N, and longitude, 104°3'W and 111°3'W (27° W and 34° W of the Washington Meridian), making the shape of the state a latitude-longitude quadrangle. Wyoming is one of only three states (along with Colorado and Utah) to have borders along only straight latitudinal and longitudinal lines, rather than being defined by natural landmarks. Due to surveying inaccuracies during the 19th century, Wyoming's legal border deviates from the true latitude and longitude lines by up to half of a mile (0.8km) in some spots, especially in the mountainous region along the 45th parallel. Wyoming is bordered on the north by Montana, on the east by South Dakota and Nebraska, on the south by Colorado, on the southwest by Utah, and on the west by Idaho. It is the tenth largest state in the United States in total area, containing 97,814 square miles (253,340km2) and is made up of 23 counties. From the north border to the south border it is 276 miles (444km); and from the east to the west border is 365 miles (587km) at its south end and 342 miles (550km) at the north end.
Because of its extreme length and wood construction, Wyoming tended to flex in heavy seas, which would cause the long planks to twist and buckle, thereby allowing sea water to intrude into the hold (see hogging and sagging). Wyoming had to use pumps to keep its hold relatively free of water. In March 1924, it foundered in heavy seas and sank with the loss of all hands.
Wyoming was 329.5 feet (100.4m) long and 50ft 1in (15.27m) wide, with a draft of 30ft 5in (9.27m). It had a volume of 373,054 cubic feet (10,563.7m3), that is, a gross register tonnage (GRT) of 3730.54. After subtracting the volume consumed by the helm and crew quarters and other areas not suitable for cargo, she had a cargo capacity of 303,621 cubic feet (8,597.6m3), or a net register tonnage of 3036.21. Its deadweight was 6,004 long tons, that is, the weight of the ship fully loaded, including the crew, cargo (6,000 tons), fuel, water and stores, less the weight of the ship when totally empty (4,000 tons), was 6,004 long tons. It could carry 6,000 long tons of coal. Wyoming was built of yellow pine with 6" planking and there were 90 diagonal iron cross-bracings on each side.
