Nice! Terminology question: I thought that "placer" mining referred to filtering river sediments and "hard-rock" mining referred to filtering rock you break off hard ground. But you have photos of several shafts labelled as "placer" mines. So what does "placer" mean then?

I'm not exactly sure why those mines have Placer in their titles. My guess is that those were operations that started out as placer claims and later became hard rock mines when they got some money to finance the hard rock mining. Good question.

OK, that makes sense. Where did you get the names of the mines? Info about these old claims is a bit sparse.

Some of the lesser known mines are listed on Western Mining History There are quite a few in the East Fork I haven't found yet.
The more well known ones can be found in John W. Robinson's books, Mines of the San Gabriels and Mines of the East Fork.
Hugh Blanchard also talked with some of the descendants of the original miners and found some information even Robinson didn't know about. Gold Mines of Los Angeles County
