mediate valley of the river, as seen from the mountain, are low 
rounded hills, appearing white in the bright sunlight of a midsum- 
mer Kansas day, which are composed of sand washed by the river 
from the Tertiary rocks to the west and northwest forming the sand 
planes and dunes along the river valley. To the southwest of the 
mountain are the smaller valleys of East and West Bear creeks and 
near their junction the city of Ashland which is distinctly visible 
from the mountain’s summit. Along the south side of the divide 
from Mt. Jesus westward are very conspicuous cliffs of Tertiary 
rocks. Some miles to the south of these, the cliffs appear as a high 
range of bluffs, ike a mountain escarpment, of almost snowy white- 
ness. This is especially noticeable in the steep cliffs forming the 
edge of the divide between five and six miles directly north of Ash- 
land. An idea of this appearance from a close view may be 
obtained from Plate X XI, which represents a part of the Tertiary 
cliffs north of Ashland, in which a heavy stratum of Tertiary marl 
is conspicuous. ‘To the south and southwest of Mt. Jesus are the 
head-waters of Day creek about which are exposed the dolomite to 
which Professor Cragin has given the name of Day Creek dolomite. 
This rock forms a rather conspicuous stratum extending around the 
lower bluffs south of the Tertiary escarpment already described. 
This limestone was also noticed by Professor St. John who described 
it as a “gray, cherty, sometimes gypsiferous limestone, 2 to 5 feet 
thick,” which he mentioned as occurring toward the top of the Red- 
Beds, forming a marked stratigraphic feature in the slopes descend- 
ing from the highlands which rise to the north nearly 200 feet above 
this limestone.! 
On the ridge four miles northeast of Ashland the Day Creek 
dolomite is conspicuously shown while to the west of Ashland, five 
miles southwest of the above locality, it was also found at an eleva- 
tion 80 feet higher according to the barometer. This gives a dip 
of approximately 6 feet per mile to the north of east. On the slope 
of Mt. Jesus and at various other localities along this divide a 
marked dip toward the south and southeast was noticed. This ac- 
cords fairly well with the direction of the prevailing dip as deter- 
mined by Professor Cragin in northern Oklahoma and southern
