BLANCHARD OR DEFIANCE MORAINE. 599 



Findlay being about 30 feet. North of Fiudlay the thickness on the crest 

 is about 50 feet, while on the inner slope at Stuartsville it is about 25 feet. 

 In a well at McComb, a few miles to the west, rock is entered at 62 feet. 



On the outer border plain from Findlay westward to within 4 miles of 

 Ottawa rock is frequently struck at about the level of Blanchard River, or 

 but 15 to 20 feet below the level of the base of the moraine. On the crest 

 of the moraine north of Gilboa a well at Dr. Newman's residence penetrated 

 80 feet of drift. It passed through several feet of sandy material, then a few 

 feet of yellowish-brown clay, and entered blue clay at about 16 feet. A 

 well at F. J. Oren's, on the outer face of the moraine, one mile south of 

 Newman's, penetrated 70 feet of drift. It entered a stony clay near the 

 surface and passed through it to a depth of 45 feet. Here a blue sandy clay 

 nearly free from pebbles was struck, which continued about to the rock. 



Near Crawfis College, just south of the moraine, a well at Joshua 

 Powell's struck rock at 40 feet. At the railway pumping station, a feAv rods 

 south and at an altitude 7 or 8 feet lower, rock is struck at 47 feet. At the 

 latter well the material thrown out at the time of digging was mainly a blue 

 sandy clay nearly free from pebbles. There is only about 4 feet of oxidized 

 surface clay at this well, but some wells in that neighborhood penetrated 20 

 to 25 feet of sand and oxidized clay before striking the blue clay. 



At Leipsic a gas-well boring penetrated 78 feet of drift, said to be 

 mainly blue clay. Several wells in the vicinity of West Leipsic struck rock 

 at 90 to 100 feet. After passing through the sandy surface deposits, which 

 are but 10 to 15 feet thick, there is tisually an unbroken sheet of blue clay 

 (till) extending to the rock. It is said to contain some pebbles and an 

 occasional bowlder. 



At Henry Foltz's residence, 2 miles northwest of West Leipsic and on 

 the highest part of the moraine, rock was struck at 88 feet. There is 8 or 

 10 feet of sandy surface clay, beneath which is blue clay extending to the 

 rock. Three other wells in the neighborhood of Foltz's strike rock at 88, 

 95, and 96 feet, respectively. Many wells in that vicinity are obtained in 

 limestone at 90 to 115 feet. 



In the Maumee Valley, near Defiance, rock is struck at slight depth, 

 and is exposed in places in that vicinity. The drift on the neighboring 

 portions of the moraine probably has a thickness as great as the difference 

 in altitude between the valley and the moraine, or 60 to 80 feet. North
