Kansas, which he stated to be a little east of south! In Professor 
St. John’s exploration, the southerly dip was noted, for he says: 
“In the vicinity of Mt. Lookout, north of Ashland, the limestone 
horizon [Day Creek dolomite} appears at a level 25 feet lower on the 
south side than it holds in the bluffs on Bluff creek.” However the 
Professor gives the general direction of the dip for the Red-Beds of 
this region as southwesterly.2, Between five and six miles north of 
Ashland are steep Tertiary cliffs which mark the line of division 
between the high and comparatively smooth prairie to the north and 
the broken country to the south forming the upper part of the valley 
of the Cimarron river. A stratum of the Loup Fork Tertiary in 
this region is massive, from 6 to 10 feet in thickness forming a sharp 
line around the upper part of the bluffs. A good idea of this 
stratum with the weathered, softer Tertiary grit below and above 
may be gained from Plate XXI, the photograph for which was 
taken directly north of the city of Ashland. The cliffs for a number 
of miles are very conspicuous from the city of Ashland and from 
points even farther south. Five miles north of the eastern line of 
Ashland, on sections 18 and 19, township 32 s., range 22 w., is a good 
exposure of the Loup Fork Tertiary and Kiowa shales with a sand- 
stone at the base. 
Section five miles north of Ashland.
