Site is located south of Antioch, California, in a former lignite and
sand mine in the Black
Diamond Mines Regional Park, under the auspices of the
East Bay Regional Park District.
- Vault/Borehole conditions:
The instruments are sited approximately 150 meters into an old mine tunnel.
There is a ~100 meter overburden composed of sandstone, shale, and coal,
which limits thermal fluctuations. In addition, 7 centimeters of foam
cover the instruments.
