MOUNT VICTORY MORAINE. 543 



In the shoulder east of the main Scioto lolie no well-defined morainic 

 belts occur which can be correlated with the Broadway moraine, but, as 

 stated in the discussion of the Powell moraine, there are occasional develop- 

 ments of morainic topography in that district between the main s}'stem and 

 a later system following nearl}^ the Mississippi-St. Lawrence di^dde. These 

 fragmentary moraines are probably correlatives of the well-defined moraines 

 in the northern part of the Scioto Basin. The ruggedness of the district 

 within the shoulder may have prevented the formation of continuous belts. 



MOUNT VICTORY MORAINE. 



This is the northernmost of the moraines that are crossed by the Scioto 

 above Columbus. It is well developed from Mount Victory in south- 

 eastern Hardin Count}^ eastward to the meridian of Marion, a distance of 

 about 20 miles. It may also be traced for 2 or 3 miles northwest from 

 Mount Victory. This brings it nearly to the Scioto River, where it becomes 

 merged with the later, stronger, Wabash moraine. Eastward froiii Marion 

 there seems to be no continuation of this moraine, for a comparatively flat 

 tract extends for several miles in that direction. Along the headwaters 

 of the Olentangy, however, there are drift knolls, which in places are so 

 closely aggregated as to give the appearance of a moi-aine, and it seems 

 probable that the continuation of the ice margin at this time of halting was 

 along that line. For some reason not yet determined, the southeast limb 

 of all the moraines crossing the Scioto Basin above Columbus is much 

 weaker than the remainder of the belts. In the Powell moraine the south- 

 east limb, though very narrow compared with its breadth elsewhere, is 

 sufficiently strong to leave no doubt as to its course, but in the Broadway 

 moraine it is only by close comparison with the bordering tracts that one 

 can decide upon the course of the belt. In the Mount Victory moraine this 

 limb is practically wanting for several miles, so that no clew to its course 

 was found; the belt is well defined only at intervals along the Olentangy. 



Where well defined the Mount Victory moraine has a breadth of 1 to 

 2 miles. It does not rise much above the plain south of it, thougli for 

 several miles it determines the eastward course of Rush Creek, and at the 

 Scioto, on each side of the stream, it has an abrupt outer border relief of 25 

 feet or more. Between the Scioto and Rush Creek the inner (northern) 

 border is more abrupt than the outer and the descent from the moraine 

 northward to the river is more rapid than it is southward.
