On the tenth of July 2008, it was decided to organize an Istigari revival trip to Wayne Tamdween: the underground river of the Western High Atlas, the suburb of Agadir.

Objective: To survey the Wayne Timduin Cave, develop a topographical map of it as a reference for each study, identify the esoteric biological diversity in the cave, and discover the largest subterranean karst network in the African continent.

In this event, a group of interested interested parties participated:

Individuals from the Istigour Sports Association in Agadir and Mstgouroun from the Istigouran Association in the city, as well as Mstgouroon from the French Alpine Club and activists from the French Federation of Istigour.

The discoveries of these invaders show the strangeness of the place, with its rigidities, formations and creatures

who have adapted to live here far from the light.

Their study also focuses on bats, the only mammals that frequent the farthest place in the caves, and how the creatures that live here in the dark places of the earthly realms are guided and guided, in an attempt to decipher the mystery of “Win Timdwin”: the region's pulsating artery.
