yond the Red hills in the general southwestward range of the Cimar- 
ron series, I did not ascertain: but from the summit of these hills the 
eye may follow the ashen ledges of its sinuous outcrop southward till 
distance dissolves them in the general landscape. 
The Taloga Formation. — On Two-mile creek and other parts of the 
Big Sandy creek drainage in adjoining parts of Meade and Clark coun- 
ties, Kansas, the Hackberry shale scarcely differs from the rocks of the 
Kiger which appear there above the Big Basin sandstone. This sand- 
stone maintains its full thickness as far west as Johns creek, on the 
right side of which it is still the highest bed of the Kiger in some forty- 
five feet of that division that appears in a bluff about a mile southeast 
of Cash City.* Here it presents a tripartite color-phase, its eight to 
twelve feet of thickness being mostly red, but about two feet at the 
base and a like amount at the summit being gray. West of Johns 
creek it is thinner. It appears in a left side bluff of lower Gyp creek, 
i)ut with only the lower and gray zone developed as quarry-rock, the 
remainder passing into shale. Several of the buildings of Englewood 
and Cash City have been made from the Big Basin sandstone of Gyp 
and Johns creeks, chiefly in the gray color. On the wrest side of Big 
Sandy creek, below its junction with Gyp creek, the thickness of this 
sandstone is only five to seven feet, and on the south side of Two-mile 
creek, where a high bluff exposes a few score feet of Kiger rocks, it is 
reduced to three feet. 
Owing to the lateness of the hour of my visit to the red hills of Blaine 
county, Oklahoma, time sufficed only for the examination of their 
northeast section, and the rocks which succeed the Day Creek dolo- 
mite immediately to the westward were not observed closely enough to 
afford positive knowledge of their character. But rocks belonging to 
the position of the Hackbery shale and Big Basin sandstone and, far- 
ther westward, others belonging to still higher horizons of the Kiger 
division are visible from the summit of these hills. 
The persistence of typical Hackberry shale and Big Basin sandstone 
in central Oklahoma is at least doubtful, while observations made south- 
west of Watouga and on the South Canadian river, in D county reveal a 
great thickness of Kiger rocks above the Day Creek dolomite, in this 
part of Oklahoma. For this reason a three-fold parting of the Kiger 
division seems to be the only practicable one, if we restrict this division 
to Cimarron rocks higher than the Dog Creek. Thus the formations of 
the Kiger division would be: the lowest, or Red Bluff: the middle, or 
Day Creek: and the highest, or Taloga; the latter n^med after the town 
of Taloga, county seat of D County, Oklahoma, being here proposed to 
include all of the Kiger rocks above the Day Creek. 
In west-central Oklahoma, some of the red rocks of the Taloga pre- 
sent a remarkable resemblance to those of the Red Bluff formation 
which are seen in the northeastern part of Barber county, Kansas, hav- 
ing the same texture and intensely red color, and giving rise to the same 
*The Cash City referred to in this article is the kiter location of the town. It is 
now the ranch of Mr. B. H. Campbell.
