As a surveyor for the International Boundary Commission, Joe Harrietha “works the line” in locating and maintaining the vast Canada–United States border. The Canadian section of the Commission is part of Natural Resources Canada, and he’s worked in some of the most remote and scenic areas in Canada for more than 25 years. These photos are from some of his expeditions. Read his personal account of one of these missions here.
