The Southwest Rift of Kilauea on Hawaii.
There's a vast and fascinating volcanic history sitting here.
Layers of rock that were made of pieces that were tossed
through the air.
Glass that froze in the air as it was thrown as molten little
bits from the volcano, and then other sorts of layers.
Then there's been a great cracking here, probably an
inflation from underneath as melted rock is moving
underneath that sort of bubbles things
up and breaks it.
Then an eruption happened at some point, and there was
actually sort of a waterfall of melted rock, and it was
flowing into the crack.
And we can see behind me all these places where this stuff
has flown down into the crack.
Just a wonderful record of the excitement of the geology of
this place.
