The high desert landscape of the Utah-Colorado border is defined by complex drainage systems and dramatic topography in this 1954 topographical study. In the southern portion of the map, the Lower Lisbon Valley stretches across the terrain, separated from the northern canyons by the narrow Lisbon Gap. This area represents a critical intersection of jurisdictional boundaries, where the border between Montrose County and San Juan County meets the state line.
