Pfad der Pioniere 04: Sonnenterrassen

Because the Albula Valley runs in a north-south direction, the sun rarely shines down to the valley floor. It is usually colder here than on the higher southern slopes. The south-facing slopes are better suited for agriculture and settlements because of the higher solar radiation. In the Albula Valley, the glaciers have further improved these good conditions by forming terraces and laying the foundation for fertile soils with their deposits. To this day, the villages are located in a privileged location on the relatively flat terraced soils.
