Abstract

Through dynamic evaluation of present slope retreat in the area, pedestal pillars and uncomformities within pinnacles are explained in terms of slump and slide processes. Cliff blocks coming down from ledges of ignimbritic mesas, and stopping at tlifferent points above the slope, can preserve the less resistant material beneath from future erosion. Fossilization potential, significance, and relations with other ignimbritic structures are here discussed.
