Book excerpt: Excerpt from Geologic Map of the Rochester and Ontario Beach Quadrangles The hight Of the lowest area on the map is on the shore of Lake Ontario which is 247 feet above tide. The highest points are in the vicinity of the Mendon hills, approximately 850 feet above tide. The higher elevations are due to drift accumulations upon the soft Salina strata. The city Of Rochester is situated nearly in the center Of the map and many fine rock sections are shown along the Genesee river well within the city limits, while the numerous steam and trolley roads running from the city make most Of the other areas of the map readily accessible. On the north, the area mapped is bounded by Lake Ontario. From the northwest corner of the map the lake shore extends in a southeast direction as far as Irondequoit bay, from which point a northeast direction is assumed, making within the limits of this map the most southerly projecting point Of Lake Ontario in New York. At the place where the lake has its greatest southern extension, Irondequoit bay Opens. This bay, representing undoubtedly an unfilled preglacial channel, and though less than 5 miles in length, is the southernmost bay Of this lake. The ridge road or the shore line Of ancient Lake Iroquois passes across the map from both sides Of the Genesee river in a nearly east and west line, having a slight northerly trend. The ridge road, while a conspicuous topographic feature, is not con fined to any particular rock formation and is not to be confused as to its origin with the ridges or escarpments due to the erosion Of the northerly edges Of the southerly dipping rocks Of this region.
