This new feature by independent filmmaker, artist, and canoeist Bill Mason (Cry of the Wild) describes a lyrical journey through the white-water rapids and swamp country around Lake Superior. On the same program is another Chicago premiere: Judith Hadel and Wade Black’s Dorothy Molter: Living in the Boundary Waters, a documentary featurette about a contemporary folk hero of northern Minnesotaa backwoods settler who spent 56 of her 79 years in the Boundary Waters canoe area and a spiritual grandmother of the north woods who has been widely celebrated in the media for her strength, endurance, and individuality. Although Molter is a fascinating film subject, the ultraconventional film treatment that she’s given here tends to sentimentalize her unconventionality without digging too deeply into its implications. Hadel and Black will be present at the Friday and Saturday screenings.
