Indiana Dunes

Wind, and therefore waves, blowing down Lake Michigan (on both sides), results in southward sediment transport and the accumulation of sand towards the south end of the lake. Here on the southeastern corner, the sand has built a robust series of dunes (many of them now well back from the advancing shoreline and largely transformed into forested ridges separated by linear wetlands).

These photos don't show it, but I could see the Chicago skyline across the lake (still a long ways away). What you do see in these photos are the stacks of steel mills and generating plants in the middle distance. It's nice that the Indiana Dunes (a State Park) preserve some natural shoreline on a coast that has suffered historically from intense industrial development (and much now in disrepair).


Ironically, today's wind was blowing strongly from the south and this leeward shore was welcome relief. I actually modified my route the last couple of days specifically to avoid the strong winds blowing north along Michigan's shoreline. By tomorrow (September 4th), unfortunately, they will be from the north again as I turn the corner and ride into Chicago.
