There is slill Miiotlicr case of the same thiuii- in section :">. Kh>oniiniiton 

 Township, which touches tlie almost covereil spur last mentioned on 

 the east and extends to Itolan. east side of section :!. The little villa.t;*' of 

 Dolan lies in the yap. or sa.t;-. lietween tlie knob and tlie simr of ni»land 

 separating;- Hean from Muddy Fork. Had the valley tloui's of tlicse re- 

 spective streams been ajj'.yraded some twenty-tive fet4 above tbeii' jiresent 

 level, the attached .spur would ha\e passed into the "island" type, as the 

 tloois of the two valleys would in that case have* been continent. 



Additional illnstiationi-i nn.uiit lie appended, but the above series is 

 siittieient to brini; out llie v;iriations in topog-raphic relief whicli fiu'uish 

 a key to this iiarticulai- stauc in the Iiistory of the valley. 



In a \\'ord. tiien. we may say tliese \arious i)hases of to)io.iirapliic relief 

 ai'e not conlincd to a limited ]iart ol the valley within Monroe ('(junty. 

 but are prominent featni'cs 1 lii-onulinnt its eiitii-e course. Moi-eovcr. tliey 

 exist as in<'vitalile conseciueiu'es resultinj;' from processes of a.ii.urading 

 and lience may lie used as leji'itiniate and trustworthy criteria by which 

 to determin(> a jiart of the life liistoi-y of the resjicctive valley.
