In 1877, the city of Tombstone was founded by Ed Schieffelin.
At the time, there was a scouting voyage in Tombstone against the Chiricahua Apaches. Ed was part of this mission and was staying at a place called Camp Huachuca. During his stay, he would leave the camp to look for rocks within the wilderness despite the fact that fellow soldiers at his camp warned him not to. The soldiers told him that he wouldn’t find stones out in the wilderness and would only eventually find his own tombstone.
Fortunately, for Ed, he did not find his tombstone, but he did find something: silver.
