The movie Mackenna's Gold is loosely based on the Adams legend that the southwestern deserts of the USA, contain a hidden canyon guarded by the Apache gods and rich with gold. Three hundred years later, the Americans came. They heard about the legend but called it, "The Lost Adams". That was because a man named Adams saw it once or so he said. But whether he did or not, he never saw anything again because the Apache's burned out his eyes. Numerous books about, or based on the diggings, have been written. The amount of mail being sent to western New Mexico during the 1930s prompted the government to create a new post office in the area affectionately named, "Lost Adams Diggings, NM". The site, minus the post office, which later shut down, bear witness to the lust for gold that will never diminish among those who catch the fever
