There are even recently de activated “mines” in Mendocino County and
jade can be found in areas of the Russian river basin and other
rivers and creeks and land areas. A local fellow has a claim deep
somewhere in N. CA that he copters out material now and then. He
has a Rock Shop in Navarro, in the Anderson Valley in Mendocion Co.
Also “Jade Cove” in Montery County, where divers have and can (?)
find jade while diving. Not sure if removal is still allowed today
or not. There is Apple Jade in the Feather River too. We have found
jade gravel on the Navarro River Beach as well as other water ways
in this area. I even found a small Poppy Jasper hunk on the Navarro
Beach. Many parts of N. CA are loaded with HUGE Serpentine
"deposits", the precursor to Jade, if proper geological actions take
place.
