Visitor Tips and News About Surveying Goof - The Lost Forty
In Minnesota's northwoods, there is an area called The Lost Forty, a 114-acre site of virgin red pine trees that was never logged back in the 1800's. Apparently due to a surveying error, the area was mapped as a lake and the trees were never chopped down. Some trees are over 300 years old and tower over 200 ft tall.[BS Meyer, 01/02/2012]
