rock bed. At Momence some of the rook ledge has been bhisted away in 

 an effort to give a better How to the Kaiilvakee. The Wabash arch presents 

 the best exposure in the central and northern part of the State. Follow- 

 ing down the Wabash numerous outcrops occur, at Logansport, Coving- 

 ton, Merom, Vincennes and l>elow New Harmony. The rock gorges along 

 Sugar Creek below Crawfordsville afford some of the most picturesque 

 scenery within the State. Above Crawfordsville the channel is shallow 

 and touches rock only at a few places. Rocky Fork, in Parke County, 

 also has many erosive features of similar apiJearance. In Vigo County 

 many exposures occur along the tributaries of the Wabash. Along Eel 

 River in Putnam County and Clay County are some excellent examples 

 of erosion in the Mansfield Sandstone. Croy's Creek, a main tributary, is 

 lined with gorges, undercuts, vertical walls, and cliffs with steep slopes. 

 The falls of the east fork of Eel River at Cataract in Owen County are over 

 the limestone. In the eastern part of the State along Clifty Creek, Big Flat 

 Rock and Little Flat Rock there are long stretches of rock bottom and 

 bank exposures in the Devonian and Tapper Silurian. Along the channel 

 of White Water and at Madison is found some of tlie very best of scenery. 

 The rock bluffs along the Muscatatuck, as at Vernon, and the shale 

 in the beds of the streams to the south, as about Henryville, are also 

 of prominence in the southeastern part of the State. In the southwest 

 the bluffs of the Patoka are si>ecially noted. These are only a part of 

 the rock outcrops within the drift area, and in addition to the many ex- 

 posures of natural ledges may also be mentioned the great deposits of 

 conglomerate gravel which presents some rugged surfaces, as along the 

 upper Wabash and along White River to the northeast of Xoblesville. 



In the driftless area the bare rock surfaces give all sorts of weath- 

 ered forms. The sandstone areas have the most striking features, with 

 the almost vertical cliffs, rising in some cases to 200 feet or more. The 

 scenery of the driftless area is not excelled by any in the State, or along 

 the Ohio Valley, or indeed, by any in the Middle West. 



Most of the streams of the State would afford good water power; 

 many examples of good power sites are present which could be utilized 

 with little cost. Rock exposures in the bed of some of the streams afford 

 greater fall and at the same time good solid bases for dams or other 

 works to be constructed.
