The beds in the cut (RR) where we collect do not appear in the Hy cut 
but may be on the flank of a big hump. The Hy cut slopes steeply toward 
the east and probably underlies the fossil beds. Shale at the N end of 
the RR cut is probably Jeff City 
At the RR cut we have the following section 
A-massive gray, [[hackley?]] fracturing Is with Stropheodonta at top. 
Lithologically variable 
B-10" single band like that below 
C-Shaly band hard in middle but soft on top & bottom 7"-a coquina of 
Stropheodonta in places 
D-Massive limestone with irregular fracture packed with fossils 
E-Shaly Is packed with fossils a probable 2-3' more 
[[Image in left margin shows strata from bottom to top: 4 1/2'A; 10"B; 
7"C; 31"D;E. B,C,D strata bracketed with line drawn to "6689"]]
