Hi, Kamron–
I guess you are talking about those rises bracketing the Panama Deep and maybe
the Galapagos Islands.
Is it clear they are really as mesa-like as they appear on the map? Let a
number of volcanoes like the big island of Hawaii all form in a region near
simultaneously rather than one at a time in the exact spot to form a line, and
I imagine it would come out like what I see on the map; I would guess the edges
would slope off like Hawaii, which might appear sharp on a large scale map. I
do not really know what forces might shape such things, and thus even vertical
cliffs would not be too much of a surprise for me…
Note that there is no law confining the Cretaceous superplume episode or other
hot spot eruptions to the west Pacific. Thus I will hazard a wild guess that
these are from broader hot spots.
