From the Anchorage Times (1937): "The weather bureau here [Seattle] said today [November 3) it received a radiogram from the Bureau of Education ship Boxer describing a violent volcanic eruption on Yunaska Island in the Aleutian chain west of Unalaska. The Boxer said it passed 15 miles northwest of Yunaska and that the island was in flames from the eruption. The disturbance seemed to be the most violent in the center, diminishing on the east and west ends."
A UP article published in the Nevada State Journal states that Isak Lystad, captain of the Boxer, reported the eruption sighted on November 2, and that "explosions could be heard from hundreds of miles" and that "smoke, fire, and ashes were ballooned thousands of feet into the air."
