A map of the area around the Zugspitze (18th century), and the confusion about the first ascent
Cartographica Helvetica 35 (2007) 3–7
In 2006, the discovery of a manuscript map in the Munich archives of the German Alpine Club (DAV), depicting the Reintal in the Werdenfels county (Bavaria) led many people to rush to conclusions on an early ascent to the Zugspitze, Germany's highest mountain. However, this presumption soon proved unfounded. This newly found map is, in fact, an inspection map ("Augenscheinkarte") which was made around 1730 in the course of a border-line conflict between the Werdenfels county and Tyrol.
