Re: You don't own the air above your ground
You just hit on one of my points. That means the mineral rights were previously sold. That isn't necessarily a government action but a transaction tendered in the past. This means the area has a history attached. When oil prospectors originally came, they negotiated mineral rights with the original landowners (or if the land was public, staked a claim with the government), which is why the conditions are noted in the deeds.
