In the middle Lahn valley, a valley zone between the Hessian uplands, the transition from the Lateglacial to the early Holocene is marked by a characteristic
change of the landscape. The fluviodynamic conditions, the composition of flora and fauna as well as pedogenesis were primarily influenced by fluctuating
climatic conditions. That meant that people of the upper Palaeolithic and the Mesolithic met changing conditions to which they had to adapt.
This interaction between people and environment within a river landscape was investigated. Mesolithic occupation sites which were detected in the (today)
potential flooding area of the valley-floor show, that this part of the valley was used by people.
