Sam's Exotic Travels to Brown Bluff, Antarctica

Our first trip ashore and a good one.

Brown Bluff is a tuya located at the northern tip of the Antarctic Peninsula, Antarctica to the east of Hope Bay. 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.

Brown Bluff has a 1.5 km long cobble and [ash] beach rising increasingly steeply towards towering red-brown tuff [cliffs] which are embedded with volcanic bombs. The cliffs are heavily eroded, resulting in loose scree and rock falls on higher slopes and large, wind eroded boulders on the beach. At high water the beach area can be restricted. Permanent ice and tidewater glaciers surround the site to the north and south occasionally filling the beach with brash ice.
