Wrangell 1760
Start: 1760 [1]
Event Type: Other
Description: The 1760 and 1784 eruptions of Wrangell are questionable, poorly documented, and may in fact refer to a volcano other than Mt. Wrangell. Dall (1870) says that "Chechitno" smoked in 1760, and again in July 1784.
These eruptions are first reported by Grewingk (1850, translated 2003 by Fritz Jaensch) as being from Chetchina, which he says is one of the Andreanof Islands. Petroff (1884), translating Grewingk, reports 1760 and 1784 eruptions from Chechina. Also derived from Grewingk, Dall (1870) and Becker (1898) report eruptions from Chechitno in 1760 and 1784. Becker (1898) states: "Mount Wrangell lies at a distance of about 134 miles from the head of Prince William Sound, and, according to Lieut. H. T. Allen, it reaches the great height of 17,500 feet. It was steaming at the date of his visit. It is the loftiest of a group of high mountains, one of which, named Mount Blackburn by Mr. Allen, is only 30 miles from the junction of the Copper River and the Tschichitna, Chechitna, or Chittyna River. I suppose this latter mountain to be that called by earlier writers the Chechitno volcano." Translation of Shmalev (found in Juergen Kienle's files) equates the Island of Chetkhina with Great Sitkin, which has historical accouts of eruptions in 1760 and 1784. According to the Smithsonian Institution Chechitno is a synonym of Wrangell. Additionally, according to Grewingk (1850, translated 2003 by Fritz Jaensch), Mt. Wrangell was not discovered until 1819.
