Laughlin, Nevada Activities Gold mine tour in Oatman The way most old west towns were started was by finding gold, which is exactly what Johhn Moss did here in 1863. Today, you can tour through the old gold mines with 145 miles worth of tunnels concealed beneath the surface of the earth. The mine is also over 3,000 feet deep – it is impossible to drop a rock to the bottom of a shaft without hitting the sides due to the curvature of the earth.
