At Bay Shore cliffs of friable or sugary yellow brown limestone varying from a few feet to 40 feet or more in height extend continuously along the shore for a considerable distance. Here the lower terrace is several hundred feet wide but the overburden is relatively thick in most places. Northern Lime Co. quarry. Bay Shore or Standard Plant. The Northern Lime Co. of Petoskey operates a number of quarries along Little Traverse Bay for lime burning. Their plant at Bay Shore is called the Bay Shore or Standard Plant. The quarry is double, consisting of an eastern and western portion with a battery of four kilns midway between. At the time of the writer's visit the western opening was the smaller and shallower but plans were then under way for cutting through the neck separating the quarries. The developed face in the smaller quarryranges in height from 15 to 25 feet but in the other it is 35 to 40 feet. The overburden is relatively thick, varying from 3 to about 10 feet, the thickness increasing away from the shore. Locally the strata show very discordant dips. The general dip is slight and almost due south yet in the smaller quarry it averaged 5 degrees N. 45 W., resulting in a pronounced inclination of the quarry floor. Larger dips were observed but these were not maintained throughout the quarry. In the eastern quarry the dip, though not measured, was strongly to the northwest as in the smaller quarry. A quarter of a mile west of the quarry the dip is about 10 in the same direction.
