a maximum diameter of three and a half inches, so that " D " and its 

 ridge are little, if indeed any, older than " C " and its ridge. 



Around " E " and "F " the largest of the cottonwoods are almost 

 ten inches in diameter and we must probably regard them as having 

 started in 1882 or 1883. Probably the bar was thrown up by the 

 great storm of 1882 mentioned by Moseley.'^ 



Immediately to the east of the Presque Isle Light, which Avas estab- 

 lished in 1872, there branches off from the beginning of the " Long 

 Ridge " a well defined ridge, which is now being washed away by the 

 lake about half a mile from the Light House Jetty. This ridge reaches 

 a height of about twenty-one feet above the lake at this point and from 

 there continues for about a mile towards the Fog Whistle, becoming 

 lower and broken towards the east. One of the largest of the cotton - 

 woods which form the backbone of the ridge has been undermined by 

 the lake and toppled over. Where it had been cut to free the Light 

 House telephone wire it had twenty-six annual rings of growth. This 

 ridge evidently was finished, as far as the work of the waves was con- 

 cerned, about 1878 ; it was formed, perhaps, by the same storm which 

 formed Ridge No. 5 at Cedar Point (see Plate XXXVII). 



" Long Ridge " on Presque Isle begins a short distance west of the 

 Presque Isle Light, and runs nearly due east for almost two miles. 

 Near its middle it has a maximum width of about nine hundred feet, 

 narrowing towards each end. At the eastern extremity it bends sharply 

 to the south and continues somewhat brokenly for another mile. At 

 its western end the ridge can be seen to be made up of three distinct 

 components, which, however, immediately lose their identity towards 

 the east, although the alignment of the cottonwoods would indicate 

 formerly separate ridges. Long Ridge has an estimated height of 

 twenty or more feet above the lake, and rises often to a height of seven 

 and a half or eight feet above the neighboring sand-plain. It is every- 

 where covered with cottonwoods, and much red cedar and white pine 

 at the western end. The largest of the cottonwoods, on the north side 

 of the ridge, measured twenty-two inches in diameter, while towards 

 the south side of the ridge the cottonwoods are older and appear to be 

 dying out. This inner (south) side of the ridge, next to Yellow Bass 

 Pond, has red cedars up to eight inches in maximum diameter, while, in 

 the depression near the union of Long Ridge with the outer ridge, 

 there is a clump of white pines reaching a maximum diameter of four- 

 teen inches.
