On Clear Lakes Ln in Buhl just west of of 1500 there is an access rd with a chain and sign that reads entering land managed by Idaho Fish and Game. I believe this rd leads to an old abandoned shack that you can see coming down the Clear Lakes grade. My son and I would like to go metal detect around that old shack but don't want to do anything illegal. Is that something we are allowed to do. The sign did not say anything about keeping out or no trespassing.
The area that you describe is part of the Niagara Springs WMA and you are free to access it. However, removing any object of archaeological, geological, or historical value or interest is prohibited on lands owned or controlled by the Department of Fish and Game.
