writes that a megalith currently found at the Presidio of Monterey is known inter alia as the Rumsen Sacred Rock, Indian Ceremonial Rock viz. Boulder, or simply as the Rain Rock.
We will use the name Rumsen Rock to refer to this megalithic boulder, because the designation "sacred rock" can not be rightly used, as no one up to now has known the rock's original purpose, sacred or otherwise, so naming it "sacred" is a bit premature.
Some have even called the boulder the "Rain Rock" because of its cupules viz. cupmarks, a purported use which of course can not be right because there are cupules also on sides that can not catch rain, nor does a rain rock designation explain why the cupules have different sizes and why there are so many of them. One researcher counted 43 in all. And there are figures on the rock too.
Others have affiliated the rock with the weather because of its original hill-top placement at CA-MNT-15, which, as Rock Art Oregon writes, is "a prehistoric site". California Prehistoric Site CA-MNT-15 has been described in more detail elsewhere as "a prehistoric midden and bedrock site near the Sloat Monument". John Drake Sloat was the man who claimed California for the United States.
Our decipherment of Rumsen Rock shows it to be astronomical in nature, with the cupules viz. cupmarks on the rock marking stars, especially the large ones on the top, primarily those of Virgo. Rumsen Rock could rightly be called "Virgo Rock" or the "Virgo Megalith". Our decipherment is below. Our placement of cupmarks in our decipherment drawings is subjective and will need to be confirmed in essential particulars by neutral third party researchers. Virgo is certain. The other stars are not. We relied on photographs of Rumsen Rock at http://rockartoregon.com/cupule-boulder-presidio-monterey.

As one can see from the images, the cupules viz. cupmarks of Rumsen Rock mark principally the stars of Virgo, plus the neighboring viz. stars that surround it on the perimeter, including Corvus, Crater, Coma Berenices, Boötes, Corona Borealis, Hercules, Ophiuchus, Libra, Serpens Caput, and also apparently also the stars of Scorpio and Sagittarius, although those markings are faint at best. We have erred on the side of inclusion and are certain that many of the "smaller" marks might not be duplicated by neutral third party observers. The larger marks on the top front side, however, clearly mark the stars of Virgo. One can discuss about the rest, which are not as important to this decipherment. Virgo is the chief group of stars here.
Rumsen Rock also might mark the Autumn Equinox ca. 3000 B.C. but there is no specific detail that points unequivocally to that conclusion, other than the stars chosen by the ancients for the left side edge of the megalith.
