Iowa history ranges from the natural to what’s been made by humans over many centuries. Find and hold the fossilized remains of sea creatures that lived 375 million years ago. Walk through a small-town home where one of the nation’s most infamous—and unsolved—murders occurred in 1912. Savor pastries that originated in the Netherlands before the 1840s and watch where wheat is ground into flour in a windmill first built in Denmark and then rebuilt in Elk Horn. Listen to time softly tick away in an elaborately carved clock that auto pioneer Henry Ford tried and failed to buy in 1928 for $1 million. Join writer-photographer Mike Whye on trips to the known, little-known and unknown historic places in Iowa.
