Geoland
Cover deposits are patchy, varying from bouldery felsenmeer regolith to intermittent till patches; surface age is variable owing to remnant snow fields which |
behave as local nevee glaciers possibly reworking older surface deposits; weathered soil overlies unweathered soil but it is not clear if the soil stratigraphy is due |
to weathering or reworking |
