Lachlan McLean photo
EDIT: This July-1905 clipping allows a date to be considered for Lachlan's undated image of the coal-fired Powerhouse alongside Clear Creek.
More information unearthed regards the C&S Siding and Hoosac Mill. These may help date those Lachlan images of the C&S63 and coalcar(just for you, Jim)
