Peat moss from the Ice Age lakes and swamps (IM-07)
Long-vanished glaciers left northern Indiana dotted with lakes and
large areas of low, hummocky, poorly drained land. In the cool
postglacial climate, mosses, reeds, and many other kinds of
aquatic plants flourished in these lakes, ponds, and swamps.
Each year the remains of these plants accumulated in the lake
bottoms and in the brackish waters of swampy areas. Eventually,
many of the smaller ponds and lakes were completely filled with
organic debris, which when compacted over many years formed
Thousands of acres of shallow lakebeds and swamplands have been
drained during the past hundred years, thus leaving rich muck
soils which form some of our most valuable agricultural land.
Peat moss is mined and processed for sale in several northern
Indiaa counties, but it is a little appreciated and poorly
exploited Hoosier mineral resource.
