- "Whoa. I think you woke up the dead with that blast!"
- -Marty to Doc while blasting open the entrance to the mine.
The Boot Hill Cemetery was adjacent to the Delgado Mine.
"Boot Hill" was a common name for cemeteries in the Old West where gunfighters who were shot and those who died from violent accidents were laid to rest. The name comes from the saying that they died "with their boots on", as opposed to those who died of natural causes in bed.
Marty McFly inadvertently discovered Doc Brown's tombstone in the cemetery, when Copernicus did not come when called while Doc was removing the DeLorean time machine from the mine. Marty vowed to disregard the instructions in Doc's letter about going directly back to 1985 and destroying the DeLorean, and instead travel to 1885 to save Doc from being "shot in the back by Buford Tannen over a matter of 80 dollars" (to quote the wording on the tombstone) and bring him home.
Behind the scenes
