Did you know that Minnesota has more than 17 million acres of forest? That’s more than 26,000 square miles and more than 20 percent of Minnesota’s total area! In other words, the Land of 10,000 Lakes is also home to plenty of forested land. Much of this land has been used for logging both in the past and present. But by a stroke of luck, there’s a small section of forest that was passed over during Minnesota’s heavy logging days of the 1800s. Today, it stands as one of the oldest sections of trees in the state. You can visit it, and it’s a fascinating – and beautiful – place that nature lovers and historians alike can appreciate it. Read on below to learn more:

The Lost 40 is a 40-acre section of the more than 660,000-acre Chippewa National Forest. It's in northern Minnesota, with the nearest towns being Northome, Bemidji, and Grand Rapids.

This section of forest makes up a small park called the Lost 40 Scientific and Natural Area. SNAs are found all around Minnesota and are great places to find interesting parts of Minnesota's nature or culture that aren't quite big enough to be state parks.

But what is the Lost 40, and where did it come from? The story goes back to the 1880s. Surveyors in the area mistakenly mapped the Lost 40 as Coddington Lake. The error was not caught until the 1960s!

As a result, the trees in the Lost 40 were never cut down by loggers. Unlike the surrounding trees, these were left to stand.
