The original quarry coordinates of CMN 57059 provided by C. M. Sternberg (1924 field notes, CMN) are Sec. 4, Twp. 32, R. 21, W. of 4, 50 [15.2 m] above river. A labeled map at the CMN further locates the site in the lower southwest quadrant of Sec. 4. One of us (D.B.B.) was able to relocate the site with E. Hiller in 1992 and can confirm that it is located within the lower Maastrichtian Horsethief Member of the Horseshoe Canyon Formation. EV: the conversion of the Legal Land Description to Coordinates gave me this locality
