Geological origin and condition

The Hohe Geest consists of the old and end moraines of the glacier of the Warthe stage of the Saale Ice Age (about 160,000 to 100,000 BC) coming from the northeast from Finland and Scandinavia , which covered northern Germany. The Hohe Geest is cut through by the up to twenty kilometers wide glacial valley of the Elbe and can be roughly assigned to the south of Schleswig-Holstein and the northern part of Lower Saxony through this natural border. Hamburg is essentially located in and around the glacial valley of the Elbe and therefore has a significant share in this landscape: The height differences in Harburg and Blankenese are determined by the Geest slope. The course of the B5 between Billstedt and Geesthacht clearly shows the Geest slope, the border between the high Geest and the marshland as well as the lowland riverside landscape (also called Brook ) or alluvial forest . Agricultural significance of the High Geest by the proportion fertile glacial till , by the glaciers carried sound or Lehmschollen have formed clay or clay pits.
