Book excerpt: In 1891 Minnesota established its first state park at Lake Itasca, the headwaters of the Mississippi River. In the century that followed, Minnesotans and tourists from other states have enjoyed hiking, picnicking, fishing, camping, canoeing, and skiing at Itasca and Minnesota's 64 other state parks. This helpful guide to the past in the parks will be welcomed by people who regularly visit a favorite Minnesota park, people who have set out to visit every park, and people who are newly discovering the parks' wonders.
