There is an information board here on the subject of "Gieser". Opposite there is a place to sit and a boundary stone. This marks the boundary between Krauschwitz and Weißwasser. Weißwasser was granted town rights in 1935. The stones were placed at this time and can be found in several places. Gieser are more or less elongated, damp depressions. The glacier compression caused the layers that would otherwise lie horizontally beneath the earth's surface to become steep. They thus protruded from the earth's surface. Lying flat beneath the earth's surface, the brown coal begins to weather. It oxidizes under the influence of atmospheric oxygen. Oxidation is associated with a loss of volume. This does not apply to the neighboring rocks sand and clay. The ground above the coal seam sinks. Rainwater washes fine soil material into the Gieser from the side slopes, along with leaves that are difficult to decompose. As a result, a water-retaining layer forms in the depression. The Gieser soil becomes moist, sometimes swampy or boggy. This explains the term Gieser (sometimes Jeser). It is derived from the Wendish word jezero: swamp.
