Old Boundary

The 37th Degree North Latitude marks the dividing line between the territories of Utah and New Mexico under the Compromise of 1850, which originally organized the land ceded by Mexico in 1848. When the Territory of Nevada was carved from western Utah in 1861, this line became the southern boundary of the new territory and continued to serve as such when the territory and state were enlarged by extensions to the east in 1862 and 1866, respectively. In 1867, the Nevada Legislature approved the action of Congress to add that portion of the territory of Arizona lying south of this line, west of the 114 West Longitude and the Colorado River, and east of the boundary to California. This action, taken on January 18, 1867, gave the State of Nevada the permanent boundaries it has today.
