(trips to FARB start early!)
| The BSL installs seismic instruments in a number of interesting places. These range from mines to wine cellars and from Nike missle silos to astronomical observatories. Some of the sites are more interesting to visit than others! | ||

| Accessibility to BSL sites varies. Some require helicopters or boats, while others are within walking distance of the BSL. Many of the sites are inaccessible in winter. One year, one of our engineers used a sled to ferry equipment through the snow in order to replace a failed sensor at YBH. Poison oak is widespread at several sites, making maintenance a challenge. | ||

| Working at BSL sites provides varied opportunities to interact with wildlife. Many sites attract small rodents, which build nests in the equipment. In particular, our frame-relay access devices seem to attract mice. CMB provides the opportunity to meet a few black widows. A conduit at SODB provides a nice resting place for a rattlesnake while unusual noise signals at PKD may be attributed to a local resident. Our engineers have reported lunching with a mountain lion and one of our stations proved to be the final resting place for a sheep. | ||
