Abstract
We report on very young (~0.2 Ma) and well preserved deposits of water bearing debris flows in Istok crater, Mars. Debris flows postdate the latest dust-ice mantle emplacement. A model of melting of recent snow packs is proposed as a water source in Istok crater. Asymmetry in slope degradation demonstrates that insolation-controlled slope processes (including gully formation by debris flows) are surprisingly efficient on Mars under very recent climate conditions.
