If it's easy to drive in the central part of Dar al Gani, on hard chalky soil and flat area, move below is something rather tricky. Except when you see that kind of rock. Sometimes we have a thought full of affection toward our poor tires. When we manage to clamber up to little plateaus, they turn out to be covered with limestone slabs. Calcareous stones are shattering under the wheels producing dry noises and showing sharp edges which shred pieces of rubber.
Few tires endure such torments day after day without a puncture.
Now we are in a position to draw the distribution ellipse of the fall which starts on Dar al Gani, and continues in the North-West direction above sandy valleys and small rocky plateaus. All the teams who prospect here on Dar al Gani, record as much information as possible in situ on each sample collected. More than 30000 years of dry climate have been necessary to create such data base. Another interesting point is the length, more than 24 km while wideness doesn't exceed 3 km. We can have a very good estimation of the trajectory.
