Abstract

SUGARLOAF MOUNTAIN, A MONADNOCK IN SOUTHERNMOST FREDERICK COUNTY, MARYLAND, IS FORMED BY AN ANTICLINORIUM CONTAINING LOWER CAMBRIAN (?) QUARTZITES AND INTERBEDDED PHYLLITES. QUARTZITE LEDGES FORMING SUGARLOAF PEAK, UNDERLYING STRUCTURAL TERRACES ON THE SOUTH AND WEST FLANKS OF THE PEAK, AND EXPOSED ALONG THE CREST OF STEWART HILL WERE RIVEN BY FROST AT SEVERAL TIMES DURING THE PLEISTOCENE. TORS AND SUMMIT PLATEAUX LIE ATOP THESE SHATTERED LEDGES| TALUS, CRYOPLANATION TERRACES AND BOULDER STREAMS OCCUR BELOW THEM. THE DEVELOPMENT OF SUCH EXTENSIVE PERIGLACIAL LANDFORMS IN AN AREA FAR SOUTH OF THE WISCONSINAN ICE BORDER WAS ENABLED BY THE FAVORABLE LITHOLOGY, ATTITUDE, AND ASPECT OF THESE LEDGES. (A.).
