Abstract
North-south asymmetry of steep slopes in middle latitude (30- 50) on Mars suggests differential erosion due to difference of amount of solar insolation between north and south-facing slopes. We estimate spread of formation age of asymmetric slopes by the MOLA data and restrict formation mechanism of the north-south asymmetry.
