Might want to check out this web page prior to any excavating. Tyvek

Subject: arsenic mining
Nov. 22, 2005
Hello,
I need some direction on locating information about arsenic mining methods
during the 1920s and 1930s. They were mining arsenic as their main product,
to be used in pesticides. Our site includes a 180 foot chimney that snakes
up the mountainside, in San Diego County. Any pointers?
Thanks,
S. Walter
