Immediately north of the gypseous mass some red clays are seen, 

 succeeded by variegated sandstones and nummulitic limestones having high 

 and contorted dips to the north as follows : —

punctures. In a gray shale band here, and in a limestone layer just 

 above it, small nummuliies, spiral shells, and fragments of bivalves occur. 

 Next above these, a dark compact thin oolitic-looking layer encloses frag- 

 ments of oysters, and the uppermost layer of all is highly fossiliferous, 

 containing many of the common gastropodous and bivalve shells of the 

 nummulitic limestone. Tracing this zone up the hill side a considerable
