True,
However it can have the look of a sedimentary rock, as lava flows layer on top of each other.
There are pumice layers in the Japanese islands and Taiwan that have thin layers of pumice strata.
I guess you could call it an igneous, sedimentary rock.
There is a chance this rock floated from the far west side of the Pacific. Especially during this El Nino.

Funny that there were so many boats out looking for it!
Sherm your post went viral!
