13031 Durance           Discovered 1989 Sept. 26 by E. W. Elst at the European Southern Observatory.
The Durance, a river in southeastern France, has its source in the Alps. Flowing through the départements of Haute-Alpes, Haute-Provence and Vaucluse, it passes the cities of Sisteron, Manosque and Cavaillon, finally meeting the Rhône river near Avignon.
