Construction has begun at Lake Vermillion State Park, Minnesota’s newest state park near Ely. The DNR says Lake Vermillion will be a “next-generation” state park. It will have children’s tree houses and an adventure trail with a ropes course. The hope is that the park will introduce more young families to the outdoors. Officials say the new park, along with the adjacent Soudan Underground Mine State Park, preserves 10 miles of lake shoreline, and has a “Boundary Waters kind of a feel.” Construction on a 70-site campground and day-use area should be wrapped up by about this time next year. The state bought the 3,000-acre property in 2010 for $18-million.
