The junction between the Trenton and Calciferous stages is shown 
at the fault line to the northeast of this section. Where the Glen- 
ville road crosses the fault line are extensive quarries known as 
the Weatherwax quarries.

limestone weathering grayish, and readily disin-

The exceptionally crystalline structure and great thickness of no. 
2 and 3 are unique. They resemble to some extent the gray 
crystalline limestone which caps the Trenton formation at Trenton 
Falls but are darker and less crinoidal. The loose fragments of 
the rock about the quarry seem to disintegrate rapidly. They 
become spongy and the fossils they contain are rendered obscure. 
The following species were identified from no. 2 and 3 of this 
section: 
1 Monticulipora (Prasopora) lycoperdon Say (aa) 
2 Bryozoan, probably Escharapora recta Hall (r) 
3 Protarea vetusta Hall (r) 
4 Rafinesquina alternata (Con.) Hall and Clarke (aa) 
5 Plectambonites sericea (Sowerby) Hall (c) 
6 Orthis (Dinorthis) pectinella (Emm.) Hall AG) 
Southward from this point these upper massive layers may be 
traced for some distance along the fault line. Near the point where 
the Chuctanunda creek meets the fault line there is an exposure 
of nearly 30 feet of thin bedded, dark blue, fossiliferous limestone 
with some intercalations of black shale and containing immense
