Robert Heizer excavated the Coloma sawmill (site of gold discovery) for the California Department of Parks and Recreation in the 1940s I believe - dated, yes, but possibly a source of information.

    Hi! 

    Has anybody out there got any information on construction and archaeological excavations of 19th Century millraces and/or penstocks, particularly buried wooden penstocks? Any and all information/leads would be very gratefully received.

    Thanks in advance.
