MOEAINES OF NOBTHEEN LIMB OF HUEON-EKIE LOBE IN INDIANA. 169 



and 2 or 3 miles north of it; this may be called the Rawson moraine. The Bluffton moraine 

 is so clearly developed as a distinct individual that it seemed worth while to look for others 

 and if possible to work out their relations to the Fort Wayne moraine and to Lake Maumee. 

 It was not possible to do this in detail, but the general relations were made out. 



It was thought at first that the passage of one of these moraines beneath the level of Lake 

 Maumee might account for certain peculiarities of the Maumee beach, especially for its north- 

 ward bulge between Delphos and Van Wert and perhaps for other simdar features between 

 Van Wert, Ohio, and New Haven, Ind. 



The investigation was not carried far enough to test this matter fully. It was found that 

 the northward bulge of the beach east of Van Wert is in all probabdity due to a moraine passing 

 lakeward, but this moraine was not identified with either the Bluffton or the Rawson moraines, 

 but appears to be inside of both of them and of later date. The area west and northwest of 

 Lima was not examined in enough detad to make sure of the identity of the Bluffton and 

 Rawson moraines west of Ottawa River. But west of the meridian of Delphos more moraines 

 of the same character and having the same relations to the Fort Wayne moraine were found 

 and followed into Indiana. Besides the faint moraine which causes the bulge of the shore 

 east of Van Wert, there is another which passes northwest from Gonway, Ohio, and affects 

 the shore slightly; it is probably continuous with a faint ridge H- mdes south of Van Wert. 



At Landeck, 3 mdes southwest of Delphos, there is a ridge which becomes distinct a mde 

 or so northwest of Venedocia and runs thence unbroken to or beyond Monroeville, Ind. Through 

 much of this distance, especially toward the northwest and in Indiana, this ridge is distinctly 

 double and throughout nearly the whole distance it is sharply defined by a well-developed 

 channel of ice-border drainage along its front. The flat floor of this drainage line is well devel- 

 oped at the south edge of Venedocia and is easdy followed for 2 miles westward to Little 

 Auglaize River. Long Prairie ditch, which comes in from the west at this point, follows the 

 bed of this glacial stream in a reverse direction. The channel itself continues west, passing a 

 mde north of Ohio City and past Glenmoore, receiving headward tributaries of Town Creek 

 between these two towns. North of Glenmoore the moraine turns northwestward, but the 

 drainage channel continues westward to Wren and thence southwest through the front ridge 

 of the Fort Wayne moraine to St. Marys River. From Glenmoore northwest to Middlebury 

 and perhaps to Wolfcale the ground hi front of the moraine is a flat floor without any evidence 

 of border drainage, but near Wolfcale a smaller border drainage channel begins and is particu- 

 larly well defined from Wolfcale to Monroeville between the two paraUel ridges of the moraine. 



Eastward from Venedocia the moraine is somewhat fainter to Auglaize River, 1 mile north- 

 east of Southworth. The drainage channel also becomes fainter in the same interval and was 

 not clearly made out at Southworth, but it may be there, nevertheless, for the tract between 

 Southworth and Cairo has not been examined. This ridge between Venedocia and Monroe- 

 ville appears to Me inside of and hence is probably later than the Bluffton moraine, but may 

 be the westward continuation of the Rawson. 



In Ohio, west of Auglaize River through southern Van Wert County, the minor drainage 

 strongly suggests another moraine and line of ice-border drainage between the one just described 

 and the main ridge of the Fort Wayne moraine, which runs close along the north side of St. 

 Marys River; and the same suggestive arrangement of drainage continues in Indiana to the 

 Maumee River. Indeed, the minor drainage southwest and west of Monroevdle indicates two 

 and probably three ridges between the Monroeville ridge and the front or main ridge which 

 passes just west of Hoagland, Ind. 



In the eastern part of Allen County, Ind., another moraine, well defined for its type, runs 

 southeastward from Gar Creek, passes just south of Dawkins, and, after crossing the State 

 line into Ohio, passes southeastward between Magdl and Batson. This moraine lies 5 mdes 

 northeast of the ridge at Monroeville and is very different from it in character. It is water-laid 

 and finds physical expression only as a very low, smooth swell or ridge in the flat plain of the 

 old lake floor. It is, however, very persistent and characteristic in its relation to the valley 

 slope. It has a definite trend in a broad graceful curve and controls the minor drainage The
