Would have been far more interesting and mysterious if it was Georgia (U.S. state).
From the Wikipedia article: "Some locals referred to its construction as 'the devil's work'. A local minister warned that "occult groups" would visit the site and that a sacrifice was imminent." Even worse: "Kandiss Taylor, a candidate in the 2022 Georgia Republican gubernatorial primary, called the Guidestones "Satanic" in a campaign ad"
With local culture this backwards, you can't expect something like this to last for long.
