Brown Bluff
Brown Bluff is a tuya located at the northern tip of the Antarctic Peninsula, Antarctica. It formed in the past 1 million years, which erupted subglacially within an englacial lake. The volcano's original diameter is thought to have been about 12-15 kilometers, and probably formed by a single vent. Brown Bluff is subdivided into four stages: pillow volcano, tuff cone, slope failure, and hyaloclastite delta and into five structural units.〔Skilling, I. P. (1994) (''Evolution of an englacial volcano: Brown Bluff, Antarctica'' ), Bulletin of Volcanology, Volume 56, Issue 6-7, pages 573-591. Retrieved on 2007-11-11〕 The volcano is named "Brown Bluff" because of its steep slopes and its brown-to-black hyaloclastite. ==Environment==
