    An old quarry, fenced and left to itself for years, developed into a beautiful nature reserve with chic little trails on the edge of the steep slopes. In the surrounding area are the Neandertal, the historic village of Gruiten and the valley of the Düssel.

    The quarry was designated in 1997 as a nature reserve. Over time, nature reclaimed the area. To marvel at the pronounced limestone cliffs, the quarry flora and rare and endangered animal and plant species. The paths are fenced and lookouts were created. Very impressive.

    The pit 7 is a former limestone quarry in the Haan district Gruiten on the edge of the forest area Osterholz on the city boundary to Wuppertal, in which dolomitisierter mass lime was mined .. Since 1997 it is designated as a nature reserve.
    At first I was astonished that the tree population was so small after 50 years of pit standstill. A research revealed, however, that he was flooded with water until just before the millennium. It served to balance the groundwater level of the entire Kalkabbaugebietes. This also explains why the white mesa was attached to the rock face. Here you could probably read off the level of the lake. The water was probably controlled at another point in the Düssel initiated, taken near the pit 7, so that the quarry flooded and if necessary, fed back into the Düssel. At some point this was no longer necessary and the pit ran dry. This explains that the tree population in the pit is not older than 20 years.

    From here you can get an idea about the mining of the limestone. The nature reserve created here not only offers us recreation-seeking space, but also benefits the plants and animals

    Wonderful viewpoint with possibility for a snack in between. Enough benches are available. Unfortunately a bit hazy today, but still a great moment to see Pit 7 in front of you and walk around it! Definitely take a little time, for children certainly also very exciting to see.
