Colorado
The State of Colorado is shaped like a rectangle. The borders are latitude and longitude lines. The four borders are at 37°N, 41°N, 102°03'W, and 109°03'W. (The east and west borders are 25°W and 32°W from the Washington Meridian.) Colorado, Wyoming, and Utah are the only three U.S. states that have only lines of latitude and longitude for boundaries and that have no natural borders. When government surveyors made the border markers for the "Territory of Colorado", minor surveying mistakes made many small kinks along the borders, most seen along the border with the "Territory of Utah."
