CHAPTER XIII. 

 MINOR MORAINES OF THE LATE WISCONSIN STAGE. 



SECTION I. MORAINES OP THE >IAUMEE-]VIIAMI LOBE. 



UNION MORAINE. 



The Union moraine constitutes the outermost member of a series of 

 moraines which he between the main morainic system of the Miami lobe 

 (discussed in Chapter XII) and the Lake Erie Basin. It is more closely 

 associated with, and bears a stronger resemblance to, the later moraines than 

 it bears to the main moT'ainic system. This moraine and the later ones 

 present smooth or gently undulating ridges comparatively free from the 

 sharp hillocks and basins which characterize the main morainic system. 

 They have, liowever, a sufficiently undulatory surface to distinguish them 

 from the bordering plains and have sufficient relief to greatly influence the 

 courses of streams. 



The breadth of these ridges differs in the different inoraines. The 

 Union moraine, the narrowest one of the series, has a general width of 

 about 1 mile. The several moraines which lie between it and the Lake 

 Erie Basin have each a general width of 2 or more miles, though locally 

 they are crowded into narrower limits 



DISTRIBUTION. 



The description is taken up at Union, a town on the State line of Ohio 

 and Indiana, from which the moraine receives its name. The moraine 

 follows the north side of Greenville Creek in a course south of east to 

 Greenville, Ohio, thence eastward to Bradford Junction, the portion between 

 Greenville and Bradford Junction constituting the point or extreme southern 

 portion of the morainic loop. The moraine bears north of east from the 

 latter village, leaving Covington about 2 miles to the south and Piqua 3 

 miles to the southeast, and comes to the Great Miami River bluff about
