A Machined Marvel in Morro Bay
Morro Rock (pictured below) was drilled and blasted for many years to create a safe harbor by placing fragments of Dacite rock into breakwater jetties.
Today, it is illegal to walk on Morro Rock, so to find ancient star holes once made along the big rock, we must travel along the breakwater jetties to find remnants of ancient drilling.
A 5-point star shaped drill hole can be found along the same cove (Coleman Cove) where the first Filipinos stepped foot onto America soil.

33 years before the pilgrims landed in Plymouth, Massachusetts (1620), a few Filipinos aboard a Spanish Galion landed in Morro Bay (1587). A few of the Filipinos were killed by Chumash Indians.
(Below) the star shaped drill hole in jetty rock at Morro Bay was not made by Chumash Indians, Spanish explorers, Filipinos, or any American in the last 250 years.
Early drill holes along Morro Rock from the 1800s until today, will have a round shape with an inside measurement less than 2 inches in diameter (1-1.5 inches ID).
(Below) round blasting holes, under 2 inches in diameter, are left over from previous blasting of Morro Rock. Because the holes are sometimes underwater, they are now covered with barnacles.
(Below) The triangle hole below does not show signs of machining. The inside walls of the triangular hole are rough with choppy, uneven walls.
The below triangular hole appears to have a clean triangular outline indicating machining; however, the hole shows choppy internal walls. Machined drill holes are smooth inside and not choppy.
To authenticate a hole as machine drilled, an image is needed inside the hole.
If the hole shows signs of irregular patterns and blunt indentations, the hole was not machined.
(Above) A triangular hole with choppy inside walls is not machined.
(Below) A triangular hole with smooth internal walls is machined.
This machined triangle drill hole found in the USA, is an example of what to look for when hunting ancient drill holes. Shaped holes with machined smooth internal walls.
The triangular shaped drill hole pictured above and the below star drill hole in Morro Bay are both machined, using an advanced drilling technology.
Ultrasonic drilling can perfectly replicate these star and triangular markings in stone.
Machined star holes are a marvel in Morro Bay, follow the rock jetties to find remnants of ancient advanced drilling.
