Corrected entry: When Marty time-travels to 1885 and stashes the DeLorean in a desert cave, a black bear inexplicably appears and chases him. There are no bears of any species that inhabit the desert badlands.

Correction: The fictional town of Hill Valley, California, is not in any desert badlands. In BTTF III, a railway map shows Hill Valley as being in Northern California, near the Sierra Nevada Mountains, where there's lots of bears.

Correction: They may not live in the badlands, but they do travel through them. Several years ago, a bear in New Mexico made a journey of 70 miles through the desert from the forested mountains to the Pecos River near Roswell.
