used to produce these data.  ·  Data represent remaining measured and indicated coal resources, analyzed
and on file, meeting minimum seam and depth criteria, and in the ground as of January 1, 2011.  These
coal resources are not totally recoverable.  Net recoverability with current mining technologies ranges from
0 percent (in far northern Alaska) to more than 90 percent.  Fifty-four percent of the demonstrated reserve
base of coal in the United States is estimated to be recoverable.  ·  Totals may not equal sum of
components due to independent rounding.
