Brown Bluff

Brown Bluff is a basalt tuya located on the Tabarin Peninsula of northern 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. The volcano is named "Brown Bluff" because of its steep slopes and its brown-to-black hyaloclastite.
