Ontario County 505 



Lake, is a hilly and broken region divided into ridges. These 

 ridges have a general north and south direction, terminating in 

 the north in a rolling region. This rolling region embraces all 

 of the county east and north of Canandaigua Lake, also that 

 portion lying west of the lake and north of the northern line of 

 Bristol. The ridges in this section gradually rise to a height 

 of from 20 to 250 feet above the valleys. A terrace with declivi- 

 ties 100 to 250 feet high, descending toward the north, extends 

 through the northern portions of East and West Bloomfiehl and 

 the southern part of Victor at right angles to the general range 

 of the ridges. 



The highest point in the county, Gannett Hill, is located just 

 west of Bristol Springs. Its height above sea level is 2,256 feet. 

 The extreme northern parts of the county are occupied by drift 

 ridges similar to those in Wayne and Seneca counties. A lime- 

 stone ridge extends across the county through the towns of Phelps, 

 Manchester, and Victor. 



The county is drained by the Honeoye Outlet, a tributary of 

 the Genesee River, and by the Canandaigua Outlet and Mud 

 Creek, tributaries of the Clyde River, and finally through the 

 St. Lawrence. A small portion of the southeast corner of Naples 

 is finally drained through Chesapeake Bay. Canandaigua Lake 

 lies almost wholly within the limits of the county. Except near 

 the head of the lake, where the shores rise in steep bluffs from 

 300 to 800 feet, the land slopes gradually down to the water. 



Honeoye, Canadice, and Hemlock lakes are smaller bodies of 

 water, each surrounded by bluffs and hills rising to a height of 

 500 to 700 feet above them. 



The soil generally consists of silty, sandy, and gravelly loam 

 formed from the drift deposits. In the valleys and the rolling 

 region that extends through the central and northern parts of the 

 county the loam is very deep and rich. On the hills in the 

 southern part the soil is made up principally of disintegrated 

 shale and slate, forming a fine, fertile grazing region. On the 

 drift hills in the west are some small sections covered with a 

 deep, light sand, moderately productive. Muck deposits are 

 scattered throughout the county to a considerable extent.
