Zone 1. Weathered surfaces predominantly blue with pink & purple patelies 

Platy, conchoidally fracturing when plates are separated. Fresh fracture finely hackly, dark gray. Contains massive beds, being finely granular, almost smooth in fracture. contains some banded dark gray - black chert that weathers

light yellow brown. Banded layers often welded into masses but fracture platy

Layering into irregular & layers separated by irregular silicious layers.

Zone 2 - Platy, predominantly yellow-weathering, light yellow to light gray in fracture, usually finely to moderately coarsely granular. Some plates fracture mouse gray, usually sparkling from calerite grains

2 - 30' - Thin,-bedded ls, yellowish surface, irregular bedding. Many trilobite fragments, Layers up to 4"
