I have no doubt that you've correctly correlated the web image and the
aerial photo with the same houses; my confusion stems from the fact that
maps show the state line to be south of this agglomeration. On the
Terraserver image, for example, there is a road coming in at an angle from
the north and intersecting with US-101. That appears from the maps to be
Stateline Road. The maps show there are three E-W streets south of this
intersection before you get to the state line. They don't appear to occur on
the Terraserver photo until you get south of the two houses where you've
placed the line.

In addition, placing the line there puts part of abandoned Chrissey Airfield
in California (remnant visible in photo). This is an Oregon State Park; I'm
not saying it's impossible for this southern end of the airstrip to be in CA
instead of OR, but I think it bears a bit more looking. I appreciate your
efforts and I guess I remain confused. I'll look into it again shortly when
I have more time.

Thanks

I'm not sure what the web site means to say. On first view, I took its
description to refer to the large house near the beach and the "crease in
the
trees" running eastward beyond US 101. I think that almost any reasonable
person would.

However, all of my labors indicate that this house is clearly in California.
It
took a lot of complex comparisons of topo maps, aerial photos, and the
California Coast web site photos to figure it out. I will try to give you
the
best evidence below.

Attached hereto is an extreme close-up of the two buildings between which I
contend that the boundary runs. Both are east of US 101. This view looks
roughly west to east, with Oregon to the left and California to the right.

Next, please go to http://tinyurl.com/2h2kj and scroll down to the aerial
photo
with grid coordinates on it. US 101 bisects the photo north to south. We
know
that BUS&SS fixes the terminal monument in latitude 41°59'55.7" twelve
chains
from the Pacific ocean. Interpolating between the latitudes shown, and
allowing
for a slight variation from photographic parallax, etc., that would place
the
boundary along the first driveway from the bottom of the picture on the east
side of the highway. Notice how this driveway curves slightly away from the
fence line down near the highway. Notice also the house just north of this
driveway--how it's surrounded by hedges and has a very round, dark tree
(split
by a blue grid line) in its back yard. Note that the building up the hill
to
the south of the driveway has a dark roof, and there are light-roofed
outbuildings in the cleared area in front of it.

Now, go back to the attached photo, taken several years later. The house on
the
left has its rows of hedges and its round, dark tree in the back yard. Up
the
hill to the right is the building with the dark roof and what appear to be
mobile homes with light roofs in the clearing in front of it. I contend
that
the boundary runs along the fence line on the north side of the driveway
near
the center of the picture.

If you need even more confirmation, go to the topo maps and locate the
California inspection station just down US 101 to the south. You can then
locate this on the corresponding aerial photos and the California Coast web
site. (On Terraserver, you can toggle back and forth between topos and
corresponding aerials--except that the aerials go one step closer-in than do
the
topos.) Once you have it on all three, work your way back northward,
comparing
the roads and houses on the west side of the highway. You will see that the
boundary is well beyond the northern end of the subdivision.
