Sand Dunes of Southern Indiana (GM-31)
We associate sand dunes with deserts, seashores and lake shores. Most notable to Hoosiers are the dunes on the south shore of Lake Michigan. But there are dunes in southern Indiana, too.

Westerly winds of late glacial time blew across valley bottoms that carried glacial meltwater and swept sand and silt from the bare dry soil in winter and deposited it in smaller dunes on the valley floor and as low rolling sandhills on the eastern bluffs. Dunes are scattered along many larger streams in southern Indiana but principally along the Wabash River, White River and East Fork of White River. Having little mineral value, they form soils unsurpassed for growing melons and other specialty crops.
