    I wonder how many animals and possibly people have fallen in that crack since its discovery

    I would probably pump 2part fast expanding closed cell foam along the thing until it was sealed over or pump a mud slurry into it until it was full, but then again I am also an advocate for bulldozing and blasting out a footing to construct a mile thick dam across the lower end of big ditch in Arizona eventually allowing it to fill to the brim with the water of the Colorado river

    If the Grand Canyon wasn't here and the forces that made it were working today, Humans would find a way to stop it...
