Minnesota may be the land of 10,000 lakes, but at one time it was also covered with magnificent forests with dozens of species of trees that were several hundred years old. Then the lumber boom of the late 19th and early 20th centuries swept through, giving us tons of building material and the legend of Paul Bunyan. Today, only 2% of Minnesota's original old-growth pine forests remain. One of those forests is called the Lost Forty.
What saved the Lost Forty? It was a surveyor's error. That particular tract was labeled as being a lake, and therefore ignored by lumber companies. You might call it a matter of not seeing the forest because of all the trees, but once a classification is committed to paper, a large lumber distributor wouldn't take the risk of harvesting those trees. The upshot is that the Lost Forty kept its trees, some up to 120 feet tall and more than 300 years old. By the time the land survey was corrected, the lumber boom was over, and the name the Lost Forty was in use. But then, another error was discovered, and it turns out the tract was actually not 40 acres, but 144 acres! That land is now part of the Chippewa National Forest.
