LAKE ESCARPMENT MORAINES. 653 



miles distant on the nortli. From the bend of Ashtabula Creek at East 

 Plymouth the Painesville moraine follows iip the south side of the creek to 

 Kelloggsville, where it crosses to the north side. The Euclid moraine hes 

 a short distance south, near the base of the rock escarpment. East from 

 Kelloggsville, the valley of Ashtabula Creek lies between the two moraines 

 to their junction at the head of the creek. 



A third ridge sets in at Ashtabula, causing the great oxbow bend of 

 Ashtabula Creek, and leads eastward through Kingsville, where it crosses 

 Conneaut Creek, and continues into Pennsylvania along the north side of 

 that stream. It is separated from the Painesville moraine only by the 

 valley of Conneaut Creek. 



The course of each of the moraines of this system in western Erie 

 County, Pa., is shown in PI. XVIII. The Euclid and Painesville moraines 

 become united at the head of Ashtabula Creek, about 6 miles east of the 

 State line, and the united moraine crosses Conneaut Creek 1 to 2 miles 

 north of Albion, just south of the great bend of the creek. From 

 Conneaut Creek it follows the base of the escarpment northeastward to 

 Elk Creek at Sterrettania, crossing Little Elk Creek near its mouth. Upon 

 passing to the north side of Elk Creek near Sterrettania it becomes difficult 

 in places to separate this moraine from the Ashtabula moraine, but g-enerally 

 a narrow sag or valley lies between the two. Mill Creek and Walnut Creek 

 each occupy this sag for a few miles. 



The Ashtabula moraine follows the north bluif of Conneaut Creek 

 eastward to the g-reat bend at Lexington. It there turns northeastward, 

 passing just west of the village of Lockport (Platea station), and crosses 

 to Elk Creek 1 to 2 miles above Girard. Upon crossing Elk Creek it turns 

 eastward and, as above noted, is separated from the Painesville moraine 

 by only a narrow valley-like depression. This depression apparently 

 fui'nished a line of westward escape for glacial waters. 



The fourth, or Girard, moi-aine is well defined and distinct from 

 moraines outside of it for only a few miles in western Erie County, Pa. 

 The western end is immediately north of Girard; but it may perhaps 

 continue as a low water-laid moraine westward along Elk Creek to the 

 shore of Lake Erie. The contours of the topographic sheet have suggested 

 such a continuation. 



Between Cross station and Girard a range of knolls and ridges
