In 1906, the city suffered a 7.9M earthquake that destroyed much of the city, leaving many people homeless. The Hill Valley Courthouse was used as a shelter for many of the victims of the disaster.
In an alternate timeline, Biff Tannen received a sports almanac detailing fifty years of sports statistics from his older self. Since he was only seventeen, he couldn't bet, so on November 13, 1955, he gave money to his grandmother to bet on the Chicago Bears. She didn't bet on the Bears, and they won against the Los Angeles Rams, making Biff twenty dollars poorer. Biff told her to make another bet, on the Washington Redskins. However, when they beat the San Francisco 49ers, she only gave Biff back his twenty dollars, and kept the rest for herself. When Gertrude claimed Biff was as greedy as his father, Biff stated that he learned that from her.
