Anomalous site behavior, such as the NUNE and MUSB episodes described above, have been removed from this analysis. The velocities are relative to stable North America, as defined by the five IGS fiducial stations. The motion of these sites relative to North America is consistent with spreading in the Basin and Range Province. These BARD results are being combined with older VLBI and spatially dense Geodolite EDM and campaign GPS measurements currently being collected by the USGS, Stanford University, and UC Berkeley. The projection is the same as in Figure 1 .
Velocities are relative to stable North America.
We currently process data available within 1 hour of measurement from the 15 continuous telemetry BSL stations, and 3 U.S. Coast Guard stations. The data are binned into 1 hour files and processed simultaneously. Several stations exhibit higher scatter than others, particularly TIBB and the USCG stations. The cause of this higher scatter is not well understood yet, but may be due to the higher multipath environment at these sites, which would have a greater effect on short interval data sets. Solutions are available within 15 minutes after the end of the hour.
