Westdahl Peak, also known as Westdahl Volcano or Mount Westdahl, is a stratovolcano of the Aleutian Range, in the U.S. state of Alaska. The volcano last erupted from November 29, 1991 to January 15, 1992. 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). Westdahl Peak currently has a summit elevation of 5,118 feet (1,560 m). 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.
