I have a colleague who has documented the archaeological remains of a
mid-20th century hog farm in Southern California (LA County). She is
curious to know if anyone else has come across a hog farm recorded as an
archaeological site (particularly in California)? She is currently trying
to evaluate the site for the National Register, but so far has not come up
with anything comparable. If anyone has an example or literature to point
us towards, would be greatly appreciated.
