I believe the Federal regulations were changed so that the National Parks would adhere to the laws of the state where they are located. And I believe anyone can carry an unconcealed weapon in California as long as it is NOT loaded. So we could potentially see people carrying weapons in Yosemite now.
It is the gun permit holders who can carry a loaded and concealed weapon.
And in California State parks, it is still illegal, by state law, to posses any weapon (Of course due to the sorry state of California's budget, a number are closing down
)
At least that's how I read the current situation. Please correct me if I am wrong.
