Abstract
Sediment sampling and a bathymetric survey of the near-shore zone of Lake Michigan between Waukegan and Zion, Illinois, provided a detailed description of the area and a basis for comparison to models of textural variation in nearshore zones. The survey, made 15-30 June 1973, yielded evidence that the breaker zone along this shoreline extends to depths of about 6 m (20 ft), that waves significantly affect the bottom to depths of 6 to 8 m (20 to 25 ft), and that some agent, probably wave action,is able to move silt and clay-sized sediment at the greatest depths of this study (15 m or 50 ft). Although the field area is composed dominantly of fine, well-sorted sands, an area of bedforms composed of coarser, more poorly-sorted sediments was found within the area. Sediments on the crests of these bedforms, now at depths of 12 to 15 m (40 to 50 ft), have characteristics in common with sediments forming the crests of longshore bars, and may represent deposits of a lower-than present lake level.
