high part of the divide terminates in the buttes known as Mounts 
Pisgah and Nebo. In the upper part of the Red-Beds along the 
biutis west of the Little Sandy are numerous conspicuous out- 
crops of the Day creek dolomite, that frequently contains nodules 
of quartz. Professor Cragin mentioned irregular nodules of 
limonite as occurring in this dolomite but did not mention chert. 
He, however, stated that the “cherty hardness and fracture are not 
due to the presence of silica, as one is tempted to infer, but are 
characters belonging to it as dolomite.” 
Mounts Pisgah and Nebo are located on the southwest quarter 
section 35, township 32 s., range 24 w., seven and one half miles west 
of Ashland and one and one half miles north. They form con- 
Sspicuous buttes visible from the southeast for a long distance. 
Section of Mount Nebo. 
Meet: 
. Top of butte, upper part marly rock, whichis sandy 21—274 
at base. Base of Tertiary. 
. Yellowish, sandy shales containing Kiowa fossils... 27—253 
Black, argillaceous shales in the lower portion of 47—226 
the steep western part of the butte. A small 
ravine at this part of the butte shows a small 
synclinal fold, the axis of which is about on a 
north and south line. 
, SUeUUbEN Or yellows, Genalchy Snes Sash sbeonoade 1—179 
. Red shales and sandstone to level Little Sandy 178—178 
creek. 
Loose on the upper part of Mt. Nebo specimens of volcanic rock 
were found. Similar specimens have also been noticed in some 
other localities in the central and western part of Clark county. 
These two buttes are west of the house of Mr. Lackey, whose ranch 
extends along the upper valley of Little Sandy creek for a number 
of miles. A view of Mt. Pisgah a Tertiary butte as seen from the 
front of Mr. Lackey’s house is given as Plate No. XXII. It is quite 
typical of the high, isolated buttes of central and western Clark 
county, especially when capped by Tertiary rock which gives to their 
Summits a more or less rounded shape. Not far to the south of
