[[/strikethrough]] Independencis 
On N side quarry in a small pit independ. zone makes floor and about 1 
1/2' above. Has only independencis in it. Over this occurs Rens zone 
beds. Also found Rens. in beds that seem to be just with or under 
independ. 
In and over the Rens. beds come granular layers with large Spirifer and 
Spinatrypa & large Schizophoria This suggests independ. zone but it 
does not have independ. I think it belongs to Profunda
