This tri-point is marked by International Boundary Monument 475, also known as the Crown Monument. The best way to reach this point from the US side is to follow the forest road shown on the topo map to Rhubarb Pond. In September, 1999 it was not possible to cross the pond's outlet because beaver activity had flooded the road. Proceed on foot up the boundary ridge to a saddle point between the northernmost point in NH and the tri-point. Follow the boundary vista east to the tri-point or west to NHN. Please note that the USGS topographic map incorrectly depicts Monument 475. The following International Boundary Commission map is correct:
