I recently purchased a historic patented mine. There is an extensive tunnel network but some of the tunnels leading to my property have entrances off my property on National Forest land. There used to be a tunnel claim, however, that claim has lapsed. The National Forest land has more recently been turned into Wilderness so my property lines are now surrounded by Hoover Wilderness in Inyo National Forest. It's my understanding that I have a right to access my property but I'm not sure to what extent. For example, can I access my property through the old tunnel entrance? If the tunnel entrance is caved in, but somewhat easily clearable, can I re-open the tunnel?
