"The river (RunningWaters) winds southwest, then moves back east to form the border with PhantomClan." "The Rift forms the border between MountainClan and FlightClan. It is not particularly difficult to traverse, but forms an effective barrier in times of battle." "The long log is the crossing between PhantomClan and the rest of the Clans (to FlightClan land)." There are other borders, of course, but they have no particularly distinguishin features.
