224 THE ILLINOIS GLACIAL LOBE. 



From Champaign a ridge nearly as bulky as the combined belt leads 

 southeastward through Philo. A short distance southeast of this village it 

 separates into two quite distinct ridges. One continues the southeast course 

 past Broadland and joins the outer ridge in southwestern Vermilion County. 

 The inner ridge passes eastward into Vermilion County along a line nearly 

 parallel with, and about 2 miles south of, the Wabash Railway until it 

 reaches the meridian of Fairmount, where it turns southeastward. It comes 

 to Little Vermilion River east of Georgetown and follows the north side of 

 that stream to the Wabash Valley. East of the Wabash its course is north- 

 eastward to Veedersburg, and thence eastward into western Montgomery 

 County, where it is overridden by a late Wisconsin moraine and its further 

 course lost to view. This ridge throughout its entire length is narrow and 

 low, seldom exceeding one-half mile in width, and rising but a few feet 

 above border plains. It is also scarcely so continuous as the other mem- 

 bers of the series. From Veedersburg another weak drift ridge leads 

 northward past Rob Roy to the Wabash Valley near Attica, beyond which 

 it can not be traced, because of concealment beneath later moraines. 



Returning to southwestern Vermilion County, where the Middle and 

 Outer ridges become united, and tracing their further course, one finds a 

 ridge about 2 miles wide and 50 to 100 feet high passing eastward near the 

 line of Vermilion and Edgar counties into Indiana. In places it has a 

 double crest, but in other places it is a thoroughly combined belt. For a 

 few miles on the west side of the Wabash River it is not well defined, but 

 it is easily located on the east bluff just below the mouth of Sugar Creek. 

 Its course for about 8 miles is south of east. It there curves, near the 

 village of Bloomingdale, and takes a nearly northeast course, crossing 

 Sugar Creek at a narrow gorge known as " The Shades of Death " near the 

 line of Parke and Montgomery counties. In western Montgomery County 

 near the village of Alamo, which stands on its crest, the course is again 

 changed toward the north, and it trends nearly due north to where it is 

 overridden by a moraine of the late Wisconsin series, near Wesley, Indiana. 



The course of the members of the Champaign system is such that the 

 Inner Ridge is separated from the combined Middle and Outer belt by a 

 space 15 to 20 miles in width in the district immediately east of the 

 Wabash, while west from that valley the space is 10 miles or less. The
