The first leg climbs out of Monticello onto a plateau dotted with sagebrush and juniper. The Abajo Mountains rise to the south, while the La Sal Range looms on the horizon. As you descend toward the Colorado River near Moab (if you detour via UT-128), the red sandstone cliffs of the Colorado Plateau become surreal. However, the direct route stays on US-191, crossing the Green River at Jensen and entering the Uinta Basin. This is oil and gas country; you will see pump jacks and drilling pads, but also the immense Book Cliffs bordering the north.
