Fossils and age. — The coal-bearing series in the neighborhood of 
Rock Creek and Cooper Creek near the old stage road has been known 
for thirty years or more. The geologists of the Fortieth Parallel Survey 
recognized its stratigraphic position beneath marine Cretaceous beds 
and referred it to the Fox Hills. In 1897 these beds and the adjacent 
formations were examined by T. W. Stanton and F. II. Knowlton, 
with results which have been published in a paper on the Laramie 
formation in Wyoming. a The following statements are quoted from 
that paper: 
One of the sections in which the relations of the different horizons are best exhibited 
is near Harpers station, on the Union Pacific Railroad, and within I or 2 miles of the 
original position of Miser station, which is mentioned in some of the earlier geological 
a Stratigraphy and paleontology of the Laramie and related formations In Wyoming: Bull. Geo] Soc. 
America, vol. 8, 1897, pp. 137-142.
