Geological summary
The small crescent-shaped Leskov Island lies about 50 km W of the main axis of the South Sandwich Islands, but appears to be comparable in age to volcanoes along the main arc. Only 900 m long and 400 m wide, it is bounded by steep cliffs and is the eroded remnant of a small andesitic stratovolcano. Its arcuate, NE-facing escarpment is concave toward Crater Bay, the site of the main eruptive center. A single Potassium-Argon determination gave an age of 0.5 million years, but fumarolic activity was recorded along the summit ridge in 1911 and 1964 (LeMasurier and Thomson, 1990).
