Mine tunnel at BDM Sparkling wine cellars at WENL Surface installation at FARB MHC site at Lick Observatory Accessibility to BSL sites varies. 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. Dirt road at MOD Helicopter trip to FARB 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 SODA 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.
