|Field Trip - Indiana Dunes National Lakeshore - 11 of 12

Oddity: an intradunal pond:
The Indiana Dunes offer some anomalies you might not expect. One of these is a pond just behind the first dune. Years of wind carved away the sand in this channel, all the way down to the level of the water table. A tall cottonwood grows near the pond, and other species that would not normally be part of succession this close to the shoreline flourish here. Animal life abounds, notably dragonflies and Fowler's toad, which lays its eggs in the pond. A rare insect-eating flower, the horned bladderwort, is in the foreground.
