Cross section of basaltic next exposed by erosion in Grant Ridges, 6 miles northeast of Grant, view looking southwest in sec. 3, T. 11 S., R. 9 W. Basalt in core is jointed in vertical columns and surrounded by a thin zone of platy jointing developed along the contact with white tuff. Bedded breccia overlies the tuff, and basaltic lava overlies the breccia on the far side of the cone. The tuff, chiefly rhyolitic, was erupted from Mount Taylor. Valencia County, New Mexico. 1931.
