The Sunsweep Trail connects Liberty and Ragged Points. At the trail's end on Ragged Point is a five-foot tall sculpture symbolic of international friendship. The sculpture was designed and given by artist David Barr as a symbol of international friendship to the people of the three communities in which it lies.
Barr installed polished, black granite markers at three sites along the Canadian/United States border; the most eastern marker is on Ragged Point in the Park’s Natural Area. The western-most piece is located at Point Roberts, Washington and a pair of stones are located about half-way between at Lake-of-the-Woods, Minnesota. Because this long, quiet border lies under the path of the sun as it moves from east to west, Barr’s work is called Sunsweep. The connecting aspect of the markers is in the form of the markers themselves. The arch-shaped stones, each about five feet high, are the ends of a conceptual arch anchored at each coast. In between, in Minnesota, are two wedge-shaped pieces that are keystones to the symbolic completion of the structure.
