Table Top Mountain description and information

From Miller and others (1998): "Tabletop Mountain, the eroded remains of of a pyroclastic cone encircled by flows originating from small flank vents, is 20 km northeast" of Makushin Volcano. Table Top is considered to be Holocene in age, and to represent a magmatic system separate from that of Makushin (Nye, personal commun., 2007). From McConnell and others (1997): "An 40Ar/39Ar age of 68+/-14 ka places this unit as the oldest satellite vent. Basaltic lavas and tephra from Table Top Mountain northeast of Makushin Volcano and a small, glaciated ramp of lava north and west of the cone."
