The Sandbuckel is a wooded inland dune southwest of the town of St. Ilgen , today a district of Leimen , in Baden-Württemberg . Its length is, in north-south direction, about 1200 meters, its width about 100 meters. Its highest point is 115.3 meters, so it rises about 10 meters above its surroundings. The boundary to the municipality of Sandhausen runs along its western foot .
Geographically, the Sandbuckel represents the most easterly of the dunes of the Schwetzinger Hardt . It is separated from this by a, at its narrowest point, 100 meters wide depression, through which the Leimbach ran until the late Middle Ages . After a river shift, the old course was named Seebach , it has now completely silted up. To the east, the railway line from Heidelberg to Karlsruhe forms the border, beyond which extends the St. Ilgen lowland, part of the Hardt Plains. The development of St. Ilgen begins to the north, at its southern tip there was a sand pit , which is now filled with water .
The construction of the dune began in the Younger Dryas period . That this was interrupted in the meantime, up to the present height, shows a three to five meter high layer of parabrown earth inside. It is bounded at the top by a humus horizon , the formation of which could be determined to the first half of the tenth century. The further expansion is possibly related to a phase of partial clearing in the interior of the Hardtwald in the high Middle Ages .
At the foot of the sand hump, the remains of a human settlement were discovered that could be assigned to the culture of the Cord Ceramists . In the peripheral areas, the use of individual properties as vineyards has been handed down for 1780 and 1828.
