Abstract

Data on the attitude of the cross-bedding in the Sioux, Baraboo, Waterloo, Barron, Sturgeon, Mesnard, Mississagi, and Lorrain quartzites, all of Precambrian age, are summarized. The azimuth and inclination of the cross-bedding, corrected for tilt of the beds, show a regional uniformity and a remarkable persistence through time. The prevailing southeasterly dip of the cross-laminations shows that these deposits were derived from a highland north and northwest of their present outcrops.
