5 Incredible Trees You Can Find Only in Indiana

Once upon a time, the forests of Indiana were endless. Or that was how it seemed in the 19th century, when the state produced more lumber than anywhere else in the nation. The valuable trees went first, such as black walnut and white oak. The scrubby leftovers were often burned to create farmland. At the start of European settlement, 90 percent of what is now Indiana was forest. That number plummeted to a measly 6 percent by 1922. While the forests have significantly recovered, there are still only about 2,000 acres of old-growth forest left in the state. Yet trees hold a hallowed place here. One town has graciously allowed a tree to grow on its courthouse roof for more than a hundred years. In many graveyards, markers are fashioned to look like stumps and branches. Read on for five woody wonders of Indiana, all rooted deeply in their communities.
