Site description Île Shag is located about 1 km east of the southern part of the Île du Havre aux Maisons? South Dune in the Magdalen Islands archipelago. It is a small island with a flat top, and cliffs that rise from the water?s edge. Vegetation is restricted to short grasses and other herbaceous plants. The cliffs, which are comprised of red sandstone, are irregularly shaped as a result of wind and tidal erosion. The mean annual temperature is 4.4?C, and the wind speed during summer averages about 27 km/h. The maximum tide level is about 1 metre. Access to Île Shag is possible with a small motor boat, but landing is difficult.
