Features of interest
Vertical section of 20+ ft . General lithology limestone and white to red-stained chert. Flow-laminated crinoidal grainstone and irregular (lenticular?) replacement chert bodies with abundant fossil casts. Complex relationships between grainstone and chert bodies, perhaps due to irregular limestone to chert replacement process. Local angular unconformity. Carbonate bank outflow channel?
