Little Traverse Bay

Figure 4.1 - Shaded relief map of nearshore area along the south coast of Little Traverse Bay. Onshore the surface morphology of this region is marked by glacial drumlins aligned northwest-southeast overlying the Devonian carbonate strata, of the Traverse Group (Fig.1). Nearshore and at the western end of the survey the morphology is irregular and block suggesting possible outcrops of consolidated units of glacial or Devonian strata. Further offshore a series of smooth, shore parallel (east-west) an echelon ridges 1-3m high dominate to the 25-30 m depth of the survey, especially east of Nine Mile Point. This suggests more fine grained materials in the nearshore as you progress east toward the head of the bay.
