2. Massive magnesian limestone or dolomite varying 2—102 
somewhat in thickness, of drab to whitish color, 
in places containing flint. This stratum is the 
one termed the “Day Creek Dolomite” by Pro- 
fessor Cragin, being named from outcrop near 
the head of Day creek in the south central part 
of Clark county six or seven miles southeast of 
this locality.t 
1. Partly covered slope showing frequently layers of 100—100 
bright red sandstone belonging to the Bluff creek 
division of Cragin. Level of Bluff creek. 
Along the bluff on the north side of the creek just above Messing’s 
house, the Day creek dolomite forms a conspicuous stratum at the 
top of the bluff with its base 85 feet above creek level. Between 
one and two miles north of west of Messing’s the canon of Bluff 
ereek begins. From this locality for a distance of 7 or 8 miles to the 
west of north the creek flows generally between high walls. In 
many places, for a considerable distance, these walls are nearly 
perpendicular for from 100 to 200 feet. In the lower part of the 
canon the walls of the bluff are composed of bright red shales and 
sandstcnes broken by a white stratum of Day creek dolomite. 
Frequently these bluffs of red sandstones and shales show from a 
number of rods to a mile or more in length with a hight of from 
50 to 100 feet giving a most excellent idea of the general character 
of the rocks forming the upper portion of the Red-Beds, or Kiger 
formation. About 3 miles above Messing’s on the west side of the 
creek is a conspicuous ledge of the Kiger formation, above which 
is a stratum 10 feet or more in thickness composed of gray soft sand- 
stone; and above this is a layer containing immense numbers of 
small Gryphaeas. Wollowing this are blackish shales 5 feet in thick- 
ness above which is another calcareous layer containing numerous 
Specimens of fossils belonging to a number of species. The 
Gryphaea bed of limestone is very similar in appearance to the 
Champion shell-bed near Belvidere. If this limestone represents 
the Champion shell-bed it would seem to follow that the subjacent
