Au Bronze final II/IIIa, le site du Touar est implanté en bordure d'un marécage subpermanent, en relation avec des barrages travertineux développés sur le cours de l'Argens et dont les niveaux tourbeux sont datés du Chalcolithique. L'habitat qui s'y implante est saisonnier. Les ressources alimentaires de ce groupe humain sont principalement liées à la chasse et à l'élevage, les terres exploitées étant encore de superficie restreinte. La datation C14, après correction dendrochronologique, est de 1400-1030 av. J.-C. Ultérieurement, des apports détritiques remblaient le marécage qui transgresse ; le site n'est plus habité mais toujours utilisé. Au premier Age du fer, le milieu est plus sec et l'habitat devient permanent. La vie pastorale est alors mieux organisée mais c'est l'agriculture qui est désormais dominante dans l'alimentation. L'augmentation des volumes de céréales à stocker se traduit par l'apparition de grands récipients de réserve et cela antérieurement aux sollicitations économiques du monde méditerranéen. Le site est abandonné au début du Ve s. av. n. è.

The presentation of the results of the investigations carried out in the cave of "Hasard" since 1967 forms the first part of two papers on two sites in the gorges of the Cèze, in the regional contexte. To the typological and stratigraphie descriptions of the fillings are added those of the movable objects excavated in the different sectors of the four explored halls. The catalogue of the receptacles and objects, systematically illustrated, constitutes a rich reference collection for the Middle Bronze and the beginning of the Late Bronze Age. On the site, entirely a burial place in the Middle Bronze Age, a habitat is built in the Late Bronze II and subsequently in the Vth c. B.C., while a burial function is also maintened.

Recent preventive excavations led to the discovery of a hill-top habitat situated on the confluence of the Collostre and the Verdon in the Alpes-de-Hautes-Provence. Two phases of occupation were recognized ; the first attributed to the period 525-450 B.C. (construction in perishable material, hand-shaped pottery, few importations, etc.), the second to the period 225-125 B.C. The latter habitat is characterized by the presence of a wall provided with a gate-tower of an unusual type for southern Gaul, and by quarters arranged on terraces. Abundant objects allow a precise characterization of the aspect of the site which appears to be marked, as is the food production, by a crisis. The utter final destruction of this oppidum by fire, in the second half of the IInd century B.C. and the presence of catapult missiles allow to suppose that the site was abandoned in connexion with the campaigns of the Roman troops against the Salluvii in 124 B.C.
