   How about this. At one time the planet had rings. Rocks in the rings gently   
   collided with one another until they all reached a uniform size and   
   spherical shape. The rings' orbit gradually declined until the dust   
   dispersed over the whole planet and the heavier spherules fell along the   
   equator, here into a soft volcanic dust pillow.   
      
   Either that or Martians are deer.
