    Meet Iowa’s 400,000 Year Old Living Fossil

    Northeastern Iowa holds a 400,000 year old time capsule. Rather than vast, flat prairies, this region boasts a rolling landscape of bluffs and ravines spared by the earth-tamping force of the last Ice Age’s glaciers. And nestled in the leaf litter on rubble piles beside the region’s chilly bluffs lives a tightly-coiled, quarter-inch endangered snail.
