Archeological sites bear witness to over 3,000 years of human history along Spednic Lake and the St. Croix River. Traditional portage routes and campsites are still in use today. The St. Croix's productive forests, rich fisheries and water highway sustained early native people and supported later settlers who built the communities and resource-based economy that remain the area's mainstay. | Archeological sites bear witness to over 3,000 years of human history along Spednic Lake and the St. Croix River.
