If good fences make good neighbors, do good mountains make even better neighbors? Mountain ridges are often used to delineate borders between countries. Somtimes borders are geometric (e.g. the 49th parallel between the western U.S. and Canada) and run right up and over peaks and down the other side. Use this album to post your experiences visiting peaks that straddle more than one country. Please post pictures that actually show spots where countries come together.
