Mariscal Mountain is a large north-to-south trending plunging anticline formed during the Laramide Orogeny at the end of the Cretaceous Period (Maxwell, 1968). It has been exhumed by uplift and erosion during through the Quaternary Period to the present. Creosote bush, yuccas, and prickly pear cactus dominate the lowland landscape along the Rio Grande. This view is looking to the southeast along the River Road.
