Entre la pointe des Chats et l'anse de Locmaria s'étend un plateau rocheux particulièrement âpre. Ici le vent souffle sans contrainte. Les plantes sont rases, les roches dénudées n'offrent aucun abri. La faune et la flore ont pris acte de ces conditions, et se font discrètes. Au large, entre 5 et 25m de fond, vivent les ormeaux, essentiellement au pied des tombants.
Between the pointe des Chats and the bay of Locmaria, lies a particularly rough rocky plate. Here, the wind blows unconstrained. The plants are close-cropped, the stripped rocks do not offer any shelter. Fauna and flora took note of these conditions, and are done discrete. Offshore, at 5-25m deep, live the abalones, primarily at the foot of the reefs.

The Sanaga went on the coast during the winter 70-71, and stayed there. Severely plundered by the islanders, she was never refloated. Slowly, the ship falls apart, colouring of rust the shells that live close in her neighborhood.

Formerly the Yewdale, the Sanaga was a 73m coaster built in year 1949. On march 28th, 1971, on her way to Saint Nazaire, she ran aground while approaching the coast in the hope to collect information on her position.
