Arabia Terra, on the northern uplands of Mars, is presumed
to be one of the most ancient red planet regions. For reasons unknown,
several hills there are neatly layered shelves of dark sands on light rock,
says NASA, “wide enough to drive a truck around. The above image, showing
an area about 3 kilometers across, was taken in October 2003 by the now
defunct Mars Global Surveyor spacecraft.” Image Credit: MSSS, JPL, NASA.

I think they look like quarries that have roads that go up or down in a spiral
