The Valles Marineris is located alang the equator o Maurs, on the aest side o the Tharsis Bumfle an raxs for naurly a fowert o the planet’s circumference. The Valles Marineris seestem stairts in the wast wi the Noctis Labyrinthus, proceeds aest tae Tithonium an Ius Chasmata, than Melas an Ophir Chamata, proceedin tae Coprates Chasma, than Ganges, Capri an Eos Chasmata, finally tuimin oot intil an ootflae lade composed o chaotic terrain an finally the Northern Plains. Maist resairchers gree that Valles Marineris is a lairge tectonic "crack" in the Martian crust, furmin as the planet cuilt, affected bi the rising crust in the Tharsis reegion tae the wast, an subsequently braidened bi erosional fushions. Houaniver, naur the aestern flanks o the clift thare seems tae be some lades that micht hae been furmed bi watter or carbon dioxide.
