Here's an old thread about this subject:
There are links there that may get you the info you need.
Basic summary is that if DGIF runs the land, CC with permit is allowed, and OC technically is not.
Do not confuse National Forests with National Parks; the NP are run by a different federal agency which currently prohibits the defensive carry of arms. National Forests are owned by the federal government, but defer to the states for carry rules.
There is an ongoing, painfully slow campaign to get DGIF to lift the restriction on OC, or to get the legislature to override them, but that hasn't happened yet.
