Editing Lahn (section)

==Source area==
[[File:Lahnquelle Lahnhof.jpg|thumb|Source of the Lahn at the Lahnhof]]The Lahn is a {{convert|245.6|km|mi|adj=on|sp=us}}-long, right (or eastern) [[tributary]] of the [[Rhine]] in Germany. Its course passes through the [[States of Germany|federal states]] of [[North Rhine-Westphalia]] (23.0&nbsp;km), [[Hesse]] (165.6&nbsp;km), and [[Rhineland-Palatinate]] (57.0&nbsp;km).

The Lahn originates at the Lahnhof, a locality of Nenkersdorf, which is a constituent community of [[Netphen]] in southeastern North Rhine-Westphalia, near the border with Hesse. The source area is situated along the Eisenstraße scenic highway and the [[Rothaarsteig]] hiking trail.

The river arises in the southeastern Rothaargebirge in the Ederkopf-Lahnkopf-Rücken ridge-line natural area. This ridge is the [[drainage divide]] between the Rhine and [[Weser]], and, within the Rhine system, the watershed between the rivers Lahn and [[Sieg (river)|Sieg]].

The source is at an elevation of {{convert|600|m|ft|sp=us}} and is located southwest of the {{convert|624|m|ft|abbr=on}} high Lahnkopf. In the vicinity are also the origins of the [[Eder (Fulda)|Eder]] (5.5&nbsp;km northwest of the Lahnhof) and the Sieg (another 3&nbsp;km north). Whereas the Sieg takes the shortest route to the Rhine (to the west), the Lahn first runs in the opposite direction, paralleling the Eder for many kilometers.
