About 44 percent of the coal produced in the United States is sub bituminous.
Wyoming is the leading source of sub bituminous coal.

Bituminous coal in the United States is between 100 to 300 million years old.
It is the most abundant rank of coal found in the United States, accounting for about half of U.S. coal production.
