Hedin's third expedition,1905-08, was entirely devoted to geographical and topographical work in Persia and Tibet. In Persia he explored and mapped the great basins of its eastern areas, with their salt lakes and deserts (the Kavir), offering an explanation of the formation of these intriguing landscapes within a framework of recent postglacial climatic changes. The first volume of this work contains the narrative of Hedin's travels in Eastern Persia. The second has: Kartographische Beschreibung der Routenaufnahme; Zur Bedeutung der persischen Namen, von K.V. Zettersteen; Zur Geologie Ostpersiens auf Grund der von Sven Hedin gesammelten Gesteinsproben, von Bror Asklund. The third has a large map in 8 sections.
