(Painted 1851.) "About two miles from camp, our course was traversed by a seam of yellowish-coloured igneous rock, shooting up into irregular spires and turrets, one or two thousand feet in height. It ran at right angles to the river, and extended to the north and south, in a chain of mountains, as far as the eye could reach. One of these towers was capped with a substance many hundred feet thick, disposed in horizontal strata of different colours, from deep red to light yellow. Partially disintegrated, and lying at the foot of the chain of spires, was a yellowish calcareous sandstone, altered by fire, in large amorphous masses. In one view could be seen clustered the Larrea Mexicana, the Cactus, (King) Cactus, (Chandelier) Greenwood Acacia, Chamiza, Prosopis Odorata, and a new variety of Sedge. For a better description of the Landscape, see the sketch by Mr. Stanley." Lieut.-Col. W. Emory's Report to the Secretary of War. [P. 57.]
