The area encompasses all sandstone formations in the wider vicinity of Göttingen. Its not limited to Lower Saxony since a lot of blocs fall within the northern part of Thuringia and some can even be found in Hesse (even some limestone). The sandstone can be quite brittle in some places. It's very important that people clean their shoes before they step on rock and never boulder when the rock is wet, since wet sandstone breaks much more easily! Even overhangs and roofs can be wet after a lot of rain because the moisture seeps in from above! If holds feel wet or are you are in doubt immediately stop bouldering, accept that outdoor bouldering cannot be completely controlled and if you act irresponsibly you could ruin mega classic problems forever!!
