i've tried to look up how to get the pickaxe and the only thing i can find is people (including the wiki) saying something along the lines of "it is found at the bottom of the lake near O tower" the problem is you cannot swim down as far as i can tell and float upwards if you go too far down in the water. i've tried riding my atv down there and it almost works but would be hard to do without losing the atv in the process. i've also tried using the hook and the other thing you can use to pickup objects that you can find. does anyone know how you can get the pickaxe.
