drop-soil in Haltern Sand

Drop-soils are a testament to the climate of an area and form in permafrost areas off the edge of the ice sheet. In order to preserve such special “works of art of nature” over the long term, they have to be fixed in place before removal using the so-called varnish section method. Each varnish section is geologically unique and has an individual aesthetic. The RUHR MUSEUM is in possession of an entire Ice Age gallery of these.
