The Tarn, a 375-km-long river in southern France, has its source on the 1550-m-high Lozère montain in the Cévennes. Famous for its brutal and dangerous flooding, the Tarn is particularly appreciated for its beautiful gorges and canyons.Naming citation (20080819/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
