This section was studied chiefly for its lithological features. It pre- 

 sents an excellent exposure of the strata near the Jennings-Catskill 

 contact, the alternation of sediments of Jennings and Catskill type oc- 

 curring near the top of the Jennings formation being well shown. It 

 also exhibits the topographic features of the Chemung admirably, the 

 sandstones occupying the horizon of the upper conglomerate forming the 

 chief ridge, while the lower conglomerate forms a smaller ridge on the 

 flanks of the larger. An unusual feature is the development of conglom- 

 erates in strata that correspond to the Woodmont member in sections 

 farther west. 



VII. Section East of Woodmont Station^ 

 One of the best sections of the lower Jennings in the State is seen 

 between Woodmont and Tonoloway stations, nearly opposite Great Caca- 



' Measured by tape.
