Mt Baldy - constantly moving dunes Indiana Dunes National Lakeshore is a protected area in Indiana, located 80 km southeast of Chicago on the dunes of Lake Michigan, along its southern shore, between Michigan City in the east and Gary in the west. . It is managed by the National Park Service, an agency that also manages national parks in the United States. It was established in 1966 as a response to the growing industrialization of the lake.

Basic information:

Dunes are stable, overgrown with successive stages of vegetation. The most important stabilizing plants are: short-necked sandpit, dwarf cherry and white poplar. With these plants the dunes reach a height of up to 50 meters. As far as the coast is concerned, there are plants of later stages of succession: the Banksa pine, the blossom, the pine, the juniper - they are covered by old sand dunes in the hinterland.

The area of ​​the present park and adjacent areas, as well as the lake itself, was 9 million years ago, a lime plateau, formed by sea sediments previously located here. After the sea became a plateau, it became an arena for water and atmospheric erosion. In the place where today is a lake, once one of the main rivers of the plateau. The lake was founded by the glacier (late Pleistocene: Wisconsin). Sand dunes formed by the action of strong north winds.
