The Anchorage Daily Times (1938) reported that during the summer of 1938, "officers of the U.S. Coast and Geodetic Survey ships Surveyor and Pioneer said that "Mount Cleveland, on Chuginadak, one of the islands of the Four Mountains, which pokes its snowy head to a height of 8,500 feet, was emitting smoke and steam."
The Fairbanks Daily News Miner reported activity in July, 1938: "Indications of the eruption of Mount Cleveland on Chuginadak island are reported by a party of men at Pioneer Camp.
"In a wireless message to Dutch Harbor the members of the party report seeing sparks and hearing rumblings.
"The extent of the eruption is now [not?] known."
