"After leaving Echo you will soon notice, on the north side of the track, two curious formations. The first is a group of reddish-colored cones of different sizes and varying some, in shape, but on the whole remarkably uniform in their appearance. These are know as Battlement Rocks."
     Henry Williams 1876

There are may smaller formations that make up this large one. Some of these are Balanced Rock, Conglomerate Peaks, Magic Rock Cut, and The Obelisk.
