Features of interest
Vertical section of 20+ ft maximum tapering to zero with ground slope at either end of outcrop. General lithology gray limestone, mudstone and white chert. Irregular bedding with frequent lensing between well-developed upward thinning hard grounds, indicating shallowing upward (falling sea level). Hard grounds often overlain by thin mudstone due to temporary deepening.
