United States

In the United States, the parallel is the southern borders of Utah, Colorado, and Kansas, and the northern borders of Arizona, New Mexico, and Oklahoma. The border comes from the Kansas–Nebraska Act of 1854 when Congress divided Indian Territory into Kansas and Nebraska north of the 37th parallel. They gave the rest to the Indian Territory to the south.
