It is on Unimak Island, near the western tip of the Alaska Peninsula. The volcano has a second summit, called Faris Peak, which is actually the highest point at 5,426 feet (1,654 m).[4] Westdahl Peak currently has a summit elevation of 5,118 feet (1,560 m).[2]
Other historical eruptions, all attributed to Westdahl by the Alaska Volcano Observatory, have been reported in 1795–1796, 1827–1829, 1951, 1964 and 1978. A couple eruptions were originally reported to be from nearby Pogromni Volcano, but the peak is old, eroded and most likely hasn't erupted since Pleistocene time.[5][2]
