The technical description from my geology book says:
Rillenkarren.- Are forms of dissolution on the surface of the rocks that consist of small channels separated by sharp crests configuring a network of tight more or less parallel gullies next to each other. Its Genesis is linked to the dissolution of the rock by the sheet of water that forms on it as a local run-off.
These traps are quite common on the Jebel but very few are in perfect working order. This one on the other hand would only need the front drop-stone lifting and supported by a stick: it would then be ready for the unfortunate wolf.
In case anyone is interested: it’s at about 9500ft & unfortunately for most people, in the restricted area.
Another route that I travel for work and during this time of year; camping trips so that I can get away from the heat.
Unfortunately with images made during the summer months, it is very easy to see the different layers of pollution, sand & dust that
get trapped due to the heat.
