The twin hills below the overlook, called Attelong Acho (Black Rock), are examples of pillow lava formed underwater during ancient volcanic eruptions.

Latte stones and pottery shards provide evidence of this ancient civilization. The Spanish later created a road system that followed the coastline from Hagåtña, south through Cetti Bay to Umatac.
