They are called the “mystery booms” of the Mother Lode and they have been rattling local nerves and even the windows of a few homes for quite awhile.
The daytime only booms are heard from Mariposa County to Amador County. Residents in Copperopolis, Twain Harte and Cedar Ridge report them often on social media but they are also heard consistently in Jamestown, Valley Springs, Sierra Village and on the east side of the Sierra Nevada from Markleeville, CA to Minden, NV.
So what are they? A lot of speculators think it is granite blasting from Hawthorne, NV and the mountains carry the sound west, all the way to various locations throughout the Mother Lode.
But that is just a theory.
Most who hear the booms say it sounds like distant thunder. Those who say their windows rattle, typically ask if they are earthquakes.
We’ve linked one of the very few videos that captures the sound of the booms. You’ll have to ignore this Mariposa County resident’s heavy breathing, but if you listen carefully, you’ll hear the booms, typically two at a time.
The mystery of the “mystery booms” in the Mother Lode continues….
