Corrected entry: Doc wrote the letter (which was read by himself at the start of the movie) and it mentioned the name Clara. Marty went back to 2nd Sept 1885, and met Clara by the cliffs later on. But that letter was written 1st September 1885, before Marty arrived. How is this possible?

Correction: The letter never mentioned Clara. They didn't find out about her until they saw the gravestone.
