La prospection


Prospecter consiste à parcourir un terrain propice pour y découvrir de nouvelles cavernes.

Le prospecteur sérieux fait d'abord une recherche documentaire, étudiant cartes topographiques, rapports géologiques, photos aériennes. Il contacte aussi les autorités locales et régionales, qui peuvent souvent fournir des informations précieuses.

Le secteur de recherche bien délimité, on se déplace sur le terrain. Les phénomènes reconnus dans la phase documentaire, les secteurs jugés les plus intéressants sont reconnus les premiers. On peut alors préciser les objectifs et l'ampleur des besoins logistiques. On organisera par la suite des expéditions de prospection et d'exploration dotées du personnel, du temps et des moyens appropriés, pendant lesquelles on procédera par recherche systématique, en ratissant le terrain.

La prospection d'un secteur donné pourra ainsi durer quelques jours, et parfois quelques années!

On lira avec profit, sur ce sujet, «Découvrez le Québec souterrain», de Michel Beaupré et Daniel Caron, Québec Science éditeur 1986, pp. 63 à 68.
