Abstract
The ground conditions on a plain in Southern Sweden have been studied by means of aerial photographs (1:20,000). The area is situated on the Baltic, some metres above the present sea-level and below the highest shoreline of late-glacial time.
The bare ground shows irregularly spaced patches of sandy soil. Through their differentiated growth, the crops in the fields emphasize the irregularities and make them cleared. The aerial photograph completes the picture by showing a clear system of intercommunicating lines. The lines compose a pattern of fluvial character but with an inverted relief.
The pattern was studied as regarded its composition, formation and age. As it was situated in peat soil, radiocarbon dating could be used.
