The moraines pass the north end ofthe Grand River Basin without notable deflection from a direct ice sheet seems to have been too thin or too weak to extend a lobe intothe basin. The Euclid moraine passes south of Austinburg and East Ply-mouth, Ohio, forming the north bluff and determing the westward course ofMill Creek, while the Painesville moraine lies parallel with it and about 2 GEOLOGICAL SURVEY MONOGRAPH XLI LAKE ESCAEPMENT MORAINES. 653 miles distant on the north. From the bend of Ashtabula Creek at EastPlymouth the Painesville moraine follows up the south side of the creek toKelloggsville, where it crosses to the north side. The Euclid moraine liesa short distance south, near the base of the rock escarpment. East fromKelloggsville, the valley of Ashtabula Creek lies between the two morainesto their junction at the head of the creek. A third ridge sets in at Ashtabula, causing the great oxbow bend ofAshtabula Creek, and leads eastward through Kingsville, where it crossesConneaut Creek, and continues into Pennsylvania along the north side ofthat stream. It is separated from the Painesville moraine only by thevalley of Conneaut Creek. The course of each of the moraines of this system in western ErieCounty, Pa., is shown in PI, XVIII. The Euclid and Painesville morainesbecome united at the head of Ashtabula Creek, about
