What exactly do you mean, return to the states? This land was never owned by the state, and never will be. It is federal land, is our public lands. Yes, it would be nice to more efficiently use some of it, but not give it away. Not sell it.
They are only "Federal lands" because two socialist Presidents stole the land FROM THE STATES for political purposes in direct conflict of the Antiquities Act. The States, under their own Antiquities laws approved by the citizens of those states, had conserved these lands and the Antiquities Act specifically states that designating Federal lands should only be done to protect them and not to restrict legitimate and traditional uses.
