The walk of the stone n°17

Datum: 10/08/2021

The rocks of Renissart : Superb 250 m long outcrop of the Calestian limestone rocks whose strata are vertically straightened. These rocks are also one of the most important climbing sites in Wallonia with more than 100 practicable routes.

The hole Fré Dj'ame or hole of Brother William is named after a monk who once lived there as a hermit. This small cave piercing through the rock is perched 20 m above the Ourthe, with an opening that plunges directly into the void.

La Fontaine de Thôt  is a resurgence of one of the two underground Isbelle rivers after a journey of more than 2 km through the limestone rocks and whose losses are located downstream from the hamlet of Mélines. The speleologists discovered a part of it in a very sporting cave inaccessible to the public.

The reappearance of the l’Isbelle in the open air is one of the two underground Isbelle rivers , after a journey of almost 2 km through the limestone rocks. The losses are located downstream from the hamlet of Mélines. Most of these underground galleries are still unknown to man! This explains why the aerial course of the Isbelle is often dry and why water only flows in times of heavy rain.

Rocher de l'Ahinet a remarkable outcrop of Calestian limestone with vertical strata

highlighted by erosion. Small natural cavities can be seen here.

The losses of the l’Isbelle

Below, at the foot of the slope, when the water flows into the stream, you can see a circular pool of water which is one of the many losses of the Isbelle, and another a few metres downstream, hidden under the roots of a clump of trees. Opposite, on the other side of the valley, is a large beaver dam.

Aïve door : The Aïve cave was used as a burial place in the Neolithic period (between 6000 and 2200 BC). Coins, pottery fragments, weapons, animal skeletons and 25 human skeletons have been found.
