GLACIAL WATERS IX THE LAKE ERIE BASIN

close to the road on the south side of the creek. The several 

 altitudes west of Fredonia are estimated as follows: Whittlesey 813, 

 higher Warren 768, lower Warren 743, lake bottom 720 feet. 



Fredonia to Walnut and Silver creeks. Along this stretch of 10 

 miles the shore features are excellently developed, continuous, 

 straight, and for much of the distance the Warren beach is distinctly 

 double. Not much verbal explanation is needed as the phe- 

 nomena are clearly shown on the map. The road leading northeast 

 from Fredonia lies on the higher Warren ridge for 3^ miles, then 

 follows the lower bars for nearly 7 miles to Walnut creek. At the 

 railroad station in Fredonia the higher Warren ridge is about 8 

 feet over the railroad station which is given as 762 feet. Using 

 this as the datum the beaches near the village are : Whittlesey 

 820, higher Warren 770, lower Warren 750 feet. The cemetery is 

 on the lower Warren. 



Two miles east by north from Fredonia a conspicuous mound or 

 cone of till stands in the Whittlesey beach and has been described 

 on page 13. 



Four miles from Fredonia the higher Warren loses its distinctive 

 character and for a mile breaks up into low, disconnected bars, and 

 afterward for 3 miles is practically unrepresented, the highway 

 following the lower Warren all the way to Walnut creek. At 

 Sheridan Station on the Erie Railroad the Warren consists of two 

 low, broad sand bars between which lies the highway. Using the 

 map figure of 758 feet for the west road crossing of the railroad as 

 the datum, the altitudes at Sheridan are: Whittlesey bar 825, 

 higher Warren (cemetery) 766, lower Warren (north of road) 

 755 feet. This gives vertical intervals of 59 and 11 feet. Former 

 measurement made the intervals 60 and 10 feet. It will be found 

 that 8 miles east the same intervals occur. Northeast of Sheridan 

 for over a mile only the lower Warren ridge can be seen in the open 

 ground, but at the south-leading road 2 miles from Sheridan the 

 upper Warren reappears, and the altitudes are: Whittlesey 825, 

 upper Warren 785, lower Warren 755, the vertical intervals being 

 40 and 30 feet. From this point to Walnut creek, if miles, the 

 higher Warren is a conspicuous, strong ridge lying $ mile landward 

 of the highway with a steady vertical interval of 30 feet above the 

 lower Warren. 



Approaching Walnut creek the Whittlesey beach, which all the 

 way from Sheridan has been diverging from the Warren, acquires 

 an east and west direction, and at the creek lies on the front of 

 the Forestville delta, 2 miles south of the lower Warren, the latter 

 keeping to its northeast course.
