Have you ever been in a coal mine?
Coal deposits can be very thick and can consist of practically pure coal with very little anything else.
Our densest forests if suddenly "pushed" (I guess covered by ash or anything else, without loosing carbon) would be millimeters in width.
(Not my area of expertise.)
Yes I've been in a coal mine. What a strange stat check.
