Est, Ile de l'
"Ile de l'Est, the easternmost island in the Crozet archipelago, is a glacially eroded basaltic stratovolcano with scoria cones concentrated on its eastern flank. A metamorphosed gabbroic complex is cut by a dense network of dikes and cone sheets that fed younger volcanic rocks. The 10 x 19 km wide Ile de l'Est is the oldest of the Crozet Islands, but contains five younger oxidized scoria cones, most of which are on the eastern side of the island. The young scoria cones may be Holocene in age (LeMasurier and Thomson, 1990)."  -Smithsonian Volcano Archive
