LATEB MORAINES OF LAKE MICHIGAN, SAGINAW, AND HURON-ERIE LOBES. 265 



smooth ridge one-half to three-fourths of a mile wide. Northeastward from Murphys Lake it 

 runs along the inner base of the Mayville moraine, not in the form of a ridge but banked up 

 against the earlier ridge as a belt of morainic ground with a definite drainage line along its upper 

 edge. North of Mayville it connects with a group of large irregular drift masses that resemble 

 interlobate deposits, but which, as already noted (p. 261), seem to be largely pre-Wisconsin drift. 



Half a mile to a mil e south of East Dayton knolls of sand and fine gravel 20 to 25 feet high 

 cover a considerable part of the surface but end abruptly at the north base of the higher ground 

 in sees. 9 and 10. The higher ground is all stony till with no outwash covering. Just west of 

 the corner at East Dayton a small drainage trough runs southwest. 



The sand knolls and the little drainage trough seem to be products of border drainage at 

 or near the front of the ice when the front rested on or against the north slope at East Dayton. 

 Many kames and sandy deposits southeast of Cat Lake, in sees. 17 and 18, are probably asso- 

 ciated with streams issuing from the ice in that depression. 



YALE MORAINE. 



On the east side of the interlobate tract the Owosso moraine apparently finds continuation 

 from the vicinity of Kingston in an ill-defined, very much broken line of low morainic knolls 

 which run southeast through northeastern Koylton, central Marlette, and central Flynn town- 

 ships to the vicinity of Omard. The broken, faint character of the morainic forms in this inter- 

 val leaves their identity and correlation somewhat Uncertain. However, a better-defined 

 moraine, known as the Yale, appears 3 or 4 miles northwest of Omard and, passing a mile west 

 of this place, continues in better form southeast into Speaker Township. It passes a mile 

 southwest of Speaker as a strong ridge with its front slightly concave to the southwest. Just 

 opposite Speaker it crosses at right angles one of the large transverse ridges of this region. 

 To the south for a mile or two its expression is faint, but near Yale it begins again as a well- 

 developed ridge and runs south along the east side of Mill Creek into Kenockee Township, where 

 it becomes water-laid. 



JITNLVTA MORAINE AND BOWLDER BELT. 



From Millmgton a faint suggestion of a moraine extends northeastward toward Juniata. 

 West and northwest of Murphys Lake it is manifested by low morainic knolls and south and 

 east of Juniata its place is marked by low bowldery knolls and ridges. In sees. 15, 16, and 

 17, Fremont Township, there is another morainic mass with kames; and in sees. 1, 2, and 3 of 

 the same township and north along the east side of sees. 36 and 25, Indian Fields Township, 

 there is a high, narrow, rugged ridge which is mainly morainic but which contains also two or 

 three kames of large size. Some of the gravels here are overlain by till, having been 

 apparently overridden by a readvance of the ice. 



A well-defined bowlder belt associated with this moraine becomes prominent about a mile 

 northeast of Juniata, and runs thence northeast past the large kames just described and across 

 Wells Township into Novesta Township, where it turns eastward past Deford and Novesta and 

 extends a little way southeastward into Evergreen Township, Sanilac County. 



There seems to be no doubt that much of this bowldery belt marks the position of the ice 

 front during the building of the Juniata moraine, although it is also associated with a great 

 drainage line which followed the front of the ice for a brief time and entered Lake Saginaw, 

 probably south of Juniata. 



For 12 miles northeastward from the southwest corner of Wells Township no definite 

 morainic ridge was observed. In the central part of Novesta Township, however, a strong 

 morainic ridge runs northeast, crossing into Sanilac County from sec. 36, Elkland Township. 

 Possibly this is the northeastward continuation of the Juniata moraine, but, although it lies in 

 the trend of this moraine, such a correlation seems uncertain, not only on account of the wide 

 interval, but because the deposit as a whole seems to be more of the nature of an interlobate 

 moraine.
