Beebee Plain, Vermont
A mile west of Derby Line is the community of Beebee Plain, which, like Derby Line, straddles the international boundary with Canada. Canusa Road, whose name is a reference to its location, comes westward from Stanstead, Quebec, and lines up right along the boundary for 1/3 of a mile. Houses on the south side of the street are in the USA, while those on the north side of the street are in Canada. Though the road turns to the north, the 45th Parallel, on which the border is based, continues westwards, and runs through a house at the end of the road (a boundary marker next to the front door has been buried almost to its tip). The boundary goes through the back yard behind the house, and hits the back part of a small industrial structure. This is the Rock of Ages plant, which is otherwise mostly in Canada. Rock of Ages, based near its famous quarries in Barre, Vermont, is the largest manufacturer of granite tombstones in North America. It operates this plant to work with Stanstead Grey Granite, which is quarried locally, in Canada. The quarries are the source for many of the large granite boundary monuments along the 45th Parallel. Beyond this region, boundary monuments are generally made of metal or concrete.
