Hantke (1951) reported Tanak-Angunak active in 1897. Attempts to locate more primary descriptions of this eruption have not been successful. Tanak-Angunak may refer to Carlisle rather than Cleveland. From Miller and others (1998): "Various names were applied to Carlisle on early hydrographic charts, including Uliaga, Kigalgin and variants thereof; it was also sometimes referred to along with the western half of Chuginadak Island, as Tanak-Angunak. It is thus possible that some of the activity ascribed to Carlisle should be attributed to Uliaga or Mount Cleveland (Coats, 1950)." However, both Grewingk (1850) and Veniaminov (1840) give descriptions of Tanak-Angunak that define it as Cleveland.
