OK, the author is USian, so probably doesn't understand standard units, but a translation would be helpful.
More to the point, a 'pile' is a unit of volume, a Wales is a unit of area (and so, presumably, is a Hawai'i Big Island - which is a mouthful for a unit!) - so is he referring to the volume of an HBI? Including volcanic peaks?
We should be told.
