The area around the stream Orsundaan, which runs trough the valley Harsbacksdalen, is famous for its beautiful landscape. The upper area of Orsundaan and Harsbacksdalen is situated just south of Heby in Uppland, Sweden. Even though the area is protected by different nature conservation acts, it is difficult to find any information about the geodiversity in the area. Geodiversity, or geological and geomorphological diversity, includes the concepts of geoprocesses and geoelements. Very high geodiversity could be seen at an inventory of the geomorphology in the upper area of Orsundaan and Harsbacksdalen. Geodiversity in not only important for understanding the geological development of the landscape, which in turn can be connected to global climate changes, but it is also very important for the biodiversity in the area. Thus, it is of great importance that people working with nature conservation issues are familiar with the geodiversity in the area. This also applies to those working with development plans of the area. Furthermore, it is of interest that visitors will be given a chance to learn more about the landscape development of Harsbacksdalen and Orsundaan and for them to get an understanding of the geoprocesses and geoelements found in the area.
