It lies in the planet's northern hemisphere in a transitional zone between the heavily-cratered regions to the south and relatively smooth plains to the North. Cydonia itself is covered in numerous mesas and may have been a coastal zone if planetologists are correct in believing that the northern plains were once ocean beds.
