1932 Map of Arnold Pond

About this map

The Canada United States international boundary defines this high-country landscape in the early 1930s, where the Maine townships of Coburn Gore and Seven Ponds meet the Quebec border. The primary artery through this wilderness is State Highway No 143, which passes through the U S Customs post near Arnold Pond. This region is defined by its complex hydrology, featuring numerous high-altitude water bodies such as Crosby Pond, Big Island Pond, and Horseshoe Pond that feed into systems like the First East Branch Magalloway River. The presence of the South Boundary Road and various named brooks like Gold Brook and McKie Brook suggest a landscape managed for timber or border security. High points like Louise Mtn and Twin Peaks tower over the surrounding bogs and ponds, illustrating the challenging terrain surveyors from the U.S. Geological Survey and the International Boundary Commission documented using early aerial photography.
