Description :
The AA. report on the characteristics of several, previously unstudied, late Pleistocene spits in northern lower Michigan. Each spit developed as strong waves eroded a headland or island within the Main and/or later stages of glacial Lake Algonquin. Most have ESE to WNW orientations with prominent recurved hooks at their ends. Wind direction data provided by these spits agree with paleoclimatic models that suggest that the Laurentide Ice Sheet had developed a strong anticyclonic circulation.
