Ogallala Formation

In the northern and western parts of Barton County a hard grayish-white arenaceous limestone marked with pinkish irregular concentric bands at the top is found capping small hills at widely scattered localities. At different places, it was found unconformably overlying the Dakota formation, Greenhorn limestone, and Carlile shale. In most places it is only a few inches thick and is broken into irregular blocks of different sizes. The greatest thickness noted was in a road cut 0.4 mile south of the NW cor. sec. 21, T. 17 S., R. 12 W., where it is somewhat more than 3 feet thick (Pl. 10A). The individual areas underlain by this limestone are only a few acres in extent, although at one time they probably had wider distribution. This limestone is believed to be equivalent to the "Algal limestone" or capping limestone of the Ogallala formation of other areas (Elias, 1931, pp. 136-141; Frye, 1945, pp. 89-91). It lies everywhere above the water table and does not yield water to wells in this area.
