Lake Agassiz
​
Compaction ridges are often sinuous, oriented congruent with modern hydrology, cross-cut younger strandlines, sometimes end at deltas, and formed as a result of delayed greater subsidence of finer-grained sediment than coarser-grained sediment. Previously unmapped, abandoned stream channels of similar scale to compaction ridges are restricted to zones south of Fargo and in places transition downstream into compaction ridges.
Lake Arkona shoreline
​
The shoreline of Lake Arkona is characterized by a subtle or “washed” appearance and can be traced around the Lake Erie basin as a discontinuous ridge. This characterization is based on the notion that the lake was transgressed by a subsequent high stand known as Lake Whittlesey.
