BackgroundTable Top and Wide Bay cinder cones, at the NE tip of the triangular NW extension of Unalaska Island across the bay from the town of Dutch Harbor, blanket or fill late-Pleistocene topography. Both 792-m-high Table Top and the 640-m-high Wide Bay cones were considered to be Holocene in age, with the Wide Bay cone being among the youngest in a SW-NE-trending volcanic belt that passes through Makushin volcano (Miller et al., 1998), however, a later 40Ar/39Ar age of 68+/-14 ka was obtained from Table Top (AVO, 2005-). Table Top Mountain cone has an associated lava apron and was considered to represent a magmatic system separate from that of Makushin volcano and Wide Bay cone (Nye, pers. comm. 2008).
