Another official Alaska Native place name

I had thought that K'esugi Ridge was the only officially recognized Alaska Native place name (not counting anglicizations of Native names). Then I came across a reference to Amchixtam Chaxsxii, the official name given to an underwater seamount in the Rat Islands of the Aleutian chain. Amchixtam Chaxsxii is the only active underwater volcano in the Aleutians. It was surveyed in 2003 by University of Alaska Professor Jennifer Reynolds using remote sensing equipment. Reynolds consulted with Unangan linguist Moses Dirks to find an Unangan name for this newest of Aleutian islands.

Unlike the Dena'ina name K'esugi, the Unangan name does not follow standard orthographic conventions. The official Dena'ina name employs a k-apostrophe (even though many secondary sources omit the apostrophe) as in standard Dena'ina. The Unangan name leaves off a diacritic mark and should be more properly rendered with a hatted-x, Amchixtam Chax̂sxii.
