25-Jul-2004 -- My wife and I were helping someone move from Oregon to
California when we stopped at this confluence. There was no
way I could pass up a confluence that was actually on our
route, Interstate 5.
Interstate 5 runs from the northern border with Canada, down
through Washington, Oregon, and California, all the way to
the southern border with Mexico. It is part of the
Pan-American Highway, which stretches across North and South
America. Going north, the Pan-American Highway continues
through Canada and Alaska. Going south, it continues through
Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Costa
Rica, and Panama. If it wasn't for an undeveloped gap
between Panama and Colombia, you could continue to drive on
through Colombia, Ecuador, Peru, and Chile.
This confluence was both easy and hard to reach. The easy
part was getting to the general vicinity of the confluence.
You just drive south on Interstate 5 and carefully pull over
and park on the shoulder. The hard part was getting to the
precise spot of the confluence. Our GPS unit showed that the
confluence was on the actual on-ramp in the flow of traffic.
To get to the spot where our GPS unit showed all zeros, we
had to wait for a pause in the traffic. Then I carefully
moved over onto the road while my wife took pictures of the
GPS unit. Since we had to back away whenever we saw cars
coming, I didn't have much time to find the spot. It took
many tries, but I was able to get all zeros with an
estimated accuracy of ±8 feet.
The highway doesn't look very busy in the pictures because I
waited for gaps in the traffic so you could get a clear view
of the area. We were pleasantly surprised to see a sign on
Interstate 5 marking the 45th parallel. It was also nice to
see nature doing its thing, right next to a major highway.
