Scope and Content
The Photographs of the Yolo Base Line, California, were taken during 1881 in Yolo County by Werner Suess and show men of the
U.S. Coast and Geodetic Survey, including George Davidson, the moveable tent (Yolo buggy) used in the survey, men taking measurements,
and the camp near "Middle Base." "The Yolo Base Line" refers to Davidson's geodesic measurement of the base lines upon which
all distances in the extensive triangulation of the State of California depend. The first was the Yolo Base line measured
twice by him in 1881, of which this collection is a record, the second was the Los Angeles base line measured three times
in 1888-89. Davidson was also president of the California Academy of Sciences, a Professor of Geodesy and Astronomy, and later
a Regent of the University of California.
