A notable example is the mesa of Acoma, in Valencia county, capped with volcanic rocks; upon its summit, about 350 ft.
An exploring party sent eastward reached Acoma, and then proceeded to Tiguex on the Rio Grande, and finally to the Pecos river.
Upon its summit, according to Indian tradition, once stood the village of Acoma, but while the inhabitants were tending their crops in the plains a powerful earth movement threw down the rocky ladder by which alone the summit could be reached.
