The "crown" of Diamond Head, Alyssa Alexandria writes, "A perfect circle of megaliths arranged in a tight circle. In between each stone is a "sight" of three great mountains; Black Butte, Shasta and Ashland. This is an extremely steep conical shaped hill (like a hershey's kiss.)"
"It is also a small round nest of stones.
Along with the walls which lead up from the bottom and curve over the other side to another conical shaped hill nearby-- they all connect by rock walls."
