Von Schmidt State
Boundary Monument
|
|
This marker commemorates
the iron column erected in 1873 at the southernmost tip of the
boundary survey line run by Allexey W. Von Schmidt, U.S. astronomer
and surveyor. The line dividing Nevada and California was based
on preliminary geodetic work by Lieutenant Joseph Christmas Ives.
Ives determined the Colorado River end of the proposed oblique
California-Nevada boundary. Von Schmidt calculated and ran the
first complete survey of the boundary. His solar observations
erred slightly--the actual line now being 3/4 mile to the north. |
