CLEVELAND MORAINE. 631 



south of these large ones. The divide between Crooked Creek and Pyma- 

 tuning Swamp presents a series of basins inclosing lakelets, but well-defined 

 knolls do not appear. South of these lakelets there is a smooth gravel 

 plain leading down the valley of Crooked Creek. Being opposite the large 

 knolls, the head of this gravel plain combines with them to reveal the 

 position of the ice margin. 



The line of drift knolls in Conneaut Valley terminates on the south 

 in a large knoll or ridge called Faust Hill, about 2 miles northeast of 

 Evansburg. This hill is situated on the brow of the bluff east of Conneaut 

 Lake, its base being about 150 feet above the lake. It is 60 to 125 feet in 

 height, the highest point being near the northern end. The trend of the 

 ridge is nearly north to south, and its length is about three-eighths of a 

 mile. It appears to be composed largely of gravel and cobble and is prob- 

 ably a short, massive esker. Between this high ridge and the Harmonsburg 

 and Meadville road there are several low gravel ridges which vary consider- 

 ably in trend. North of Conneaut Lake the valley is occupied by a series 

 of knolls and basins. The knolls in the midst of the valley are 15 to 30 

 feet in height, but a few on the slopes are larger, a group southeast of 

 Conneautville being 50 to 75 feet in height and very abrupt. Northwest 

 of Dicksonburg a few knolls reach a height of about 50 feet, but have 

 gentle slopes. In Conneaut Valley the sharpest knolls and ridges are on 

 the eastern slope, but the western slope carries low swells, thus differing 

 from the valleys of Pymatuning Swamp and Cussewago Creek, whose 

 western slopes are nearly free from drift knolls. 



The southern member of this morainic belt, which leads across from Con- 

 neaut Lake to Cussewago Creek, has low drift swells 10 or 15 feet in height, 

 which, though feeble, present a contrast with bordering tracts on the north 

 and south, which have scarcely any such knolls. The northern member is 

 indicated by a gently undulating surface, the highest swells on the uplands 

 being 10 to 15 feet high. They are conical and cover from 1 to 3 acres each. 

 In this northern member, about 2 miles nearly due west from Crossingville, 

 is a conical drift hill 40 to 50 feet high, covei'ing 8 or 10 acres, and oppo- 

 site this village on the west side of Cussewago Creek are two equally 

 prominent knolls connected by a low ridge; the northern one rises very 

 abruptly to a height of 40 to 50 feet, and covers only about 1^ acres; the 

 southern one is as high, but covers 3 or 4 acres. These are well shown on
