Description
The Addington volcanic field consists of a submarine probable maar or crater with associated subtle volcanic cones [1] [2] . This field lies offshore west of Cape Addington in Southeast Alaska. The crater is about 1 km wide and nearly circular in shape; the rim is about 243 feet (74 m) below sea level, and the crater floor is about 1195-951 feet (364-290 m) below sea level. Wilcox [2] and Wilcox and others [3] identify the Baker Island black tephra as potentially sourced from the Addington volcanic field, and date it to 13,492 +/- 237 cal yr BP.Name Origin
The "Addington volcanic field" is an informal name, named after the nearby Cape Addington, by Greene, 2011.
