Today's seamount - Liszt seamount, is pretty unique in that it sits right on top of these
structural features.
These structural features are called fracture zones.
And they have been there for ninety million years or so.
You can think of them as the big cracks in the crust.
So one of the things we are curious about, is whether or not the lavas that are coming
up in these seamounts are exploiting these fractures to get to the surface because it's
an easier path for them to ascend.
Well the geology has gotten a lot more interesting as we have gone upslope.
John, what's this long tube?
That's quite impressive.
That's like a really big pillar of lava.
That's how this lava mobilizes downslope.
