Asset Impairment Charges [Abstract]  
IMPAIRMENT CHARGES IMPAIRMENT CHARGES  Quarter ended June 30, 2021. During the second quarter of 2021, we recorded impairment expense of $7.9 million related to various undeveloped land positions and related permitting costs in Australia. At June 30, 2021, we identified an impairment trigger related to certain of these properties due to the cancellation of a significant thermal coal project in Australia and our negative expectations related to other possible Australian thermal coal projects becoming viable in the near term. Accordingly, the assets were written down to their estimated fair value of $2.4 million.
