6648 - Mound of crinoidal and granular debris surrounded E, W and S 
by usual type of rock seen here, ie the smooth grained lumpy Is. 1250 
paces downstream from old barn on N side of creek 
NW corner 14-56N-6W, 
Rensselaer 7 1/2' sheet, Missouri

6649 = Slabby limestone in layers 4-5" Thick with Magistocrinus NW cor 
NW 1/4 15-56N-6W, Renssalaer 7 1/2' [[square]], Mo. 
A remarkable feature at 6646 is the wrapping of the Rensselandia beds 
from the creek bed over the fine grained hackly fractured Is. This 
suggests that Rensselandia beds are limes sands banked over hard 
layers. It also suggests that that they are likely to be spasmodic in 
occurrence
