Experience the forest of yesteryear at the Lost 40. Minnesota was one of the largest timber-producing states in the country in the late 1800s, but 144 acres of red and white pines went untouched by loggers when a surveying error mapped the area as part of Coddington Lake. The survey crew's error in 1882, became one of Minnesota's greatest treasures. Today, less than two percent of Minnesota's forested land contains old growth timber. The Lost 40 pines are 300-400 years old, originating when the pilgrims came to America. The trees remain as remnants of the natural resources that drew people to new frontiers and shaping America’s character. A one-mile, self-guided trail winds its way through the towering pines of the Lost 40.
