Tucson driving the blue spring wagon carrying the first load of silver bullion valued at $18,744 (about $ today) Tombstone founded When the first claims were filed, the initial settlement of tents and cabins was located at Watervale near the Lucky Cuss mine. By March 1879, about 100 residents occupied tents and shacks at Watervale. Former Territorial Governor Anson P.K. Safford offered financial backing for a cut of the men's mining claims, and Ed Schieffelin, his brother Al, and their partner Richard Gird formed the Tombstone Mining and Milling Company and built a stamping mill. On March 5, 1879, U.S. Deputy Mineral Surveyor Solon M. Allis finished laying out a new town site on a mesa named Goose Flats at , to top of the Tough Nut mine, and large enough to hold a growing town. The town was named "Tombstone" after Schieffelin's initial mining claim. The shelters at Watervale were relocated to the new town site and a scattering of cabins and tents were quickly built for about 100 residents. During the first few months of mining, the upper portion of the Tombstone mining district was accidentally discovered by Ed Williams and Jack Friday. Late one night, their mules broke loose and dragging their chain, left the miners' dry camp for water along an Indian trail. The men tracked the mules' chain trail all the way to the Schieffelin camp. Williams and Friday noticed a bright gleam where the iron had dragged across bare rock. They filed a claim for their find, but Al and Ed Schieffelin and Richard Gird contested their claim, asserting it violated their earlier claims. When the two parties finally resolved their arguments and counterclaims, they agreed to divide the ground. Williams and Friday took the higher end, which they called the Grand Central, and the Schieffelin company took the lower end, which they named the Contention in remembrance of the quarrel that led to its founding. Those two mines were eventually the most profitable mines in Tombstone. Some of the ore from the "Lucky Cuss", "Tough Nut", and the "Contention" mines assayed at around $15,000 to the ton. Ed Schieffelin preferred prospecting to running a mine and he left Tombstone to find more ore. When he returned four months later, Gird had lined up buyers for their interest in the Contention, which they sold for $10,000 to J.H. White and S. Denson, who represented
