Location:
The MNRC site is on property owned and formerly operated by Homestake Mining Company as a surface gold mine. The 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 McLaughlin Reserve (part of the University of California Natural Reserve System. 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.

Support for MNRC was provided by the Governor's Office of Emergency Services as part of the California Integrated Seismic Network.

Geology:
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.

Data Availability:
BDSN waveforms and associated metadata are available at the Northern California Earthquake Data Center (NCEDC).

Several tools provide access to SEED format data at the NCEDC, both in terms of querying the archives and allowing data requests.

Help on using these tools is available.
