Excerpt from The University Studies of the University of Nebraska, Vol. 2 As to the mode of occurrence, it ought to be repeated that the corkscrews occur on the Pine Ridge table lands, and stretch in area over four or five hundred square miles, as far as ex plored. In vertical range they extend through one hundred and fifty or two hundred feet, or even more. The beds lie chiefly in Sioux county, in the extreme northwest corner of Nebraska. How far they extend to the east, or to the west in Wyoming, is not determined. The Niobrara river is roughly the southern limit, and the White river, the northern. They have frequently been reported two hundred miles east of this point, and one hundred and fifty to two hundred miles south, The author has not as yet been able to prove or disprove the statements of his informants, though holding them in doubt.
