The watershed

Marker 18At the centre of the landscape, the river Malzac meanders through the relatively gentle relief and then flows into the Mimente in the Atlantic catchment area. Meanwhile the Grisoulle, on your left, is a tributary of the Gardon, which flows into the nearby Mediterranean, cutting abrupt slopes into the relief as it goes. The Grisoulle’s gradient is six times steeper than the Malzac’s. It is quite possible that in a few thousand years, the Grisoulle will capture the Malzac and profoundly alter the landscape. The little pass that separates them is the watershed, which also goes through the Castelas and Can Noire.
