Dear Brian:
If it isn't too much of an imposition, an electronic copy of Metcalf s report would be grand. Preliminary review of
this document will certainly facilitate our consultation for Sage Creek toward the end of December. I look
forward to discussing this project with you next week, and with the Thanksgiving in mind, early week(Monday
or Tuesday)would work better.
Take care and thank you for your assistance,
Mark

Creek Mine. BLM - LSFO will be the lead agency when consulting with SHPO in the future about the
effects of subsidence at the proposed Sage Creek Mine. Putting this mine into production in the years to
come will require acquisition of one or more federal coal leases that would be issued by BLM.
BLM's consultation with SHPO regarding the Sage Creek mine was "put on a back burner," but I hope to
facilitate completion of the consultation process by the end of December. Jennifer informs me that
Peabody's plans to develop the Sage Creek mine are currently on hold. Because of this, I turned my
attention to more pressing matters in recent weeks. As you mentioned, Metcalf Archaeological Consultants
(MAC) is recommending a case study that documents the condition of eligible prehistoric sites in open
terrain before and after subsidence in order to provide an evidence-based assessment of exactly what
