Adam,
I got
the same results you did. Street Atlas USA shows it missing by about 250
ft. but it
appears to be right on as a quad-point on
Topozone. Can you identify the book which
described the county boundaries?
Has anyone been to
or seen a photo of the San Joaquin-Stanislaus-
Santa Clara-Alameda county
quadripoint in California at Mt.
Boardman? Mapquest doesn't show this as a
quadripoint, but I believe
they're wrong. Topozone's USGS maps show it as
such, and I remember
reading in a book describing the legal boundaries of
the California
counties that the summit of Mt. Boardman was specifically
identified
as a quadripoint.
