The MNRC site is on property owned and formerly
operated by Homestake Mining Company as a surface gold mine.
geology of the area
is extremely varied and complex. With the conclusion of mining operations, the property
will be managed by UC Davis as the
(part of the University of California Natural
The seismographic vault is the first new research project on the reserve. The site is located
approximately 20 kilometers east of the town of Lower Lake,
California in an area of Franciscan sandstone.
- Vault/Borehole conditions:
A steel and concrete vault from a shipping container
similar to those found at stations JCC,
PKD, and HOPS was
constructed. Power and telephone lines were trenched approximately
300 meters to the site. Because of the remoteness of the site,
digital telephone data circuits are not available. Telemetry was
established in spring 2004 using a radio network that brings the
data down to Napa and into the frame-relay network.
