Over the years, the rock formations at America's Stonehenge
have been named by researchers. Mensal means "table." The slab that makes up the "table surface" is estimated to weigh 6 to 8 tons. How did it get there? On its front, you can see, marked with white paint, three modern drill marks believed to have been created by quarrymen in the 1800s. The fact that this site was quarried further reminds visitors that, as they form impressions, they must take into account that much of this stone marvel has been irrevocably altered over the years.
