690 THE JOURNAL OF GEOLOGY. 
on account of the excellent exposures along nearly every 
stream in the eastern and northern portions of the county, I 
would propose that it be called the Wabaunsee formation. 
Early geologic explorations.—The rocks of this formation 
along the Kansas River, especially from Mill Creek westward, 
were carefully examined by Meek and Hayden in the summer of 
1858, and a paper describing the geology of the region traversed 
appeared the following January.* During the same summer Dr. 
Newberry studied this series of rocks as exposed along the 
Santa Fé road, on his return from the Ives exploring expedition 
of the Colorado ‘River of the West, from Santa Fe to) Port 
Leavenworth, crossing the Neosho River at Council Grove.? 
In the summer of 1859 Dr. Newberry again crossed the same 
formations as exposed along the route from Independence, Mo., 
to Santa Fé on his way to join the Macomb exploring expedi- 
tion and described to some extent the rocks and fossils found 
along Dragoon Creek and on the high ground to the west.3 
Paleontology.—The calcareous and argillaceous shales fre- 
quently contain numerous specimens of fossils representing a 
™Proc. Acad. Nat. Science, Philadelphia, Vol. XI., p. 8; see particularly pp. 14 
and 18. A part of this paper including the “general section of the rocks of Kansas 
valley” appeared in the Am. Jour. Sci., May, 1859 (2d series, Vol. XXVII., pp. 424— 
432). 
2 Dr. Newberrys’s observations on this trip were published in 1861 in the Report 
upon the Colorado River of the West, explored in 1857 and 1858 by Lieut. Joseph C. 
Ives. Geological Report by Dr. J.S. Newberry, Chapter X., Geology of the route from 
Santa Fé to Fort Leavenworth, p. 102. See particularly pp. 110-115. Meek and 
Hayden’s “ General section of the rocks of the Kansas Valley”’ from Manhattan to 
the Cretaceous is copied on pp. 112-114. 
3 Report of the Exploring Expedition from Santa Fé, New Mexico, to the junction 
of the Grand and Green Rivers of the great Colorado of the West in 1859, under the 
command of Capt. J. N. Macomb, with Geological Report by Professor J. S. Newberry. 
See Chapter I., and especially pp. 16-21. Although Dr. Newberry’s report was fin- 
ished in 1860, it was not published until 1876, but in his Prefatory Note of June, 1875, 
we find these words: “ Precisely as written in 1860.” A brief account of this trip 
appeared in the September number of the Am. Jour. Science, for 1859 (2d series, Vol. 
XXVIII., pp. 298, 299) where Dr. Newberry states that “from Wellington to Cotton- _ 
wood and Turkey Creek the Permian was constantly found in the hill-tops, but the 
valleys were excavated down to the Carboniferous” (p. 298).
