We adjusted the three-dimensional locations of the monuments in the USGS Hollister trilateration network to fit line length observations observed in 1977. We used a Bayesian approach, incorporating prior elevation estimates as data in our adjustment procedure. We found no significant discrepancies in the measured line lengths, but significant elevation adjustments (up to 1.85 m) were needed to fit the length data.
