Being that I celebrate the entire Bill Mason catalog, figured I'd highlight this promotional mini-documentary that he did in the early eighties for the Pukaskwa National Park on the Ontario shores of Lake Superior. The Pukaskwa Park is still really young, having become a National Park in 1971 to protect the natural wonders of our northern lakes, but more specifically the Pukaskwa Pits.The Pukaskwa Pits are small holes (1-2 meters long, and half a meter deep) dug by the ancestors of the native Ojibwa. The pits are dug in the rough, cobblestone beaches along the Superior shore. Theories on the pits purposes range from hunting blinds and seasonal food storage to spiritual sites. The park itself spans 700 square miles of thick, remote hardwoods, separated by the White River on it's way to the world's largest freshwater lake.Watch Bill Mason's take on the park over at NFB.ca.
