Reclamation liability

We mine various minerals using a surface mining process that requires the removal of overburden.  In certain areas and under various governmental regulations, we are obligated to restore the land comprising each mining site to its original condition at the completion of the mining activity.  We include an estimate of this reclamation liability in our condensed consolidated balance sheets; it is adjusted to reflect the passage of time, current activities, and changes in estimated future cash outflows.  A reconciliation of the activity within our reclamation liability is as follows:
