Jackman/Armstrong Border Crossing, Maine

The Jackman/Armstrong port of entry is the northernmost paved border crossing on the western side of Maine. North of it is the remote territory of the North Maine Woods, and dirt logging roads across the border, all the way to Highway 1 at Fort Kent before the pavement begins again. Jackman/Armstrong is one of four official crossings on the section of boundary known as the Highlands. The Highlands is the divide between watersheds, where on one side water flows to the St. Lawrence River, through Quebec, and on the other side to the Gulf of Maine and Atlantic Ocean. Traveling over the top of the ridge line for more than 120 meandering miles, this section of the international boundary is among the most remote and unmonitorable on the whole continental line. It meanders, like a river, but is on high and dry land. South from Jackman/Armstrong it is another 50 miles to the next port of entry.
