The basic point is that the European powers often negotiated boundaries
without knowing the local geography. Or when the new USofA negotiated
about the West. (See Barry Smith's "On Drawing Lines on a Map"
(http://wings.buffalo.edu/philosophy/faculty/smith/articles/drawing.html)
for a general treatment but nothing about Point Roberts.)

Anyway, in the mid 1800s, the United States wanted all territory on the
Pacific Coast up to 54 degrees 40' noth, the S limit of Russian territory.
Britain on the other hand wanted the border to the Columbia River (or was
it 42 latitude?) Anyway, eventually, the compromise was negotiated to be
the 49th parallel of latitude west to the Pacific. Britain was so solidly
settled in to Vancouver Island that they convenced the US to let them
retain control of the Island. The wording of the treaty was something
like, "the 49th parallel west to the ocean, thence through the principle
channel between Vancouver Island and the mainland. There was later
argument about whteher the principle channel was east or west of the San
Juan islands but eventually the US won and the San Juans became US
territory.

Back to Point Roberts. When the treaty was worded and signed, presumably
no-one realized that the 49th parallel intersects the mainland shoreline
three times! A similar case of drawing lines on maps without knowing the
local geography led to Kentucky having a disconnected piece due to the
fact that the parallel selected for the KY-TN border crosses the
Mississippi 3 times. And a piece of Minnesota (the Northwest Angle)
similarly can be reached by land only through Canada and forms the
northernmost part of the 48 continguous states, is US territory largely
because when the treaty wording was plotted out on the geography, there
were some surprises!
