MARION LIMESTONE. 



The greater part of the time was spent in studying tlie Florence 

 fiint down to the Wabaunsee formation and the collection of 

 fossils for comparison with those of the Coal Measures. For 

 this reason, but little time was given to the higher strata. 



The Marion limestone is found in the higher of the elevations, 

 near Barnes. It is much less conspicuous than is the Florence 

 flint and limestone of the region. Above this limestone the rough 

 country of the flint hills disappears, and we have a level prai- 

 rie extending westward to the Cretaceous, which appears west 

 of Greenleaf. This limestone and the overlying Marion forma- 

 tion are found east of the Little Blue on the higher land, and on 

 to the southward, to the vicinity of Riley Center and Fort Riley. 

 It may appear also in the vicinity of Fostoria, in Pottawatomie 

 county. 



The characteristic concretions of this limestone are probably 

 present in this area, though probably less conspicuous than in 

 the southern area.
