The Missisquoi River valley carves a vital corridor through the Vermont-Quebec borderlands in this late 1970s orthophoto survey. This unique collaboration between the USGS and the U.S. Customs Service highlights the geography of international transit. The Canadian Pacific railroad parallels the river, passing through border outposts like East Richford and Stevens Mills. The aerial imagery reveals the sharp contrast between the wooded slopes of Sutton Mountain and the cleared agricultural plots near Glen Sutton and Glenton.
