Bernese Alps through which the Rhône finds its way to Lake Geneva, to the Grimsel Pass or, depending on the definition, to the river Reuss (thus including the Uri Alps). The principal ridge, a chain that runs from west (Dent de Morcles) to east (Sidelhorn), whose highest peak is the Finsteraarhorn, forms the watershed between the cantons of Bern and Valais. Except for the westernmost part, it is also the watershed between the Rhine (North Sea) and the Rhône (Mediterranean Sea). This chain is not centered inside the range but lies close (10 to 15 km) to the Rhône on the south.
Geneva and Lyons Railroad by the New York Central in 1890. Chartered on October 5, 1877, the Geneva and Lyons was built to improve the connections between the New York Central and the Syracuse, Geneva and Corning Railroad. The latter line was leased by the Fall Brook Coal Company, a major supplier of coal to the New York Central. The Fall Brook already connected to the Auburn Road of the New York Central at Geneva, but the new railroad allowed trains to run through Geneva directly to the main line of the New York Central at Lyons. This allowed the rerouting of coal traffic
