Green Mountain is a rural community in York County, New Brunswick, Canada.
Green Mountain is known for its scenic views of the surrounding area of northwestern New Brunswick and adjacent northeastern Maine, including Mount Katahdin (Maine's highest mountain) and East Grand Lake which is bisected by the International Boundary.
As time wore on, the population dwindled and farming became less attractive with the rocky and clay soil conditions.
In the year 1863, Henry Pray and George Robinson came here and moved to what is called the Balm of Gilead Point.
The mail came in once a week and it was carried part way by a team and the rest of the way on foot by Samuel Cropley.
The North Lake Post Office was located at that time what is now called Fosterville and it was kept by William Foster.
