Mt. Wilson
A map and satellite picture of the area
Then a set of pictures from the UCLA Solar
Telescope
The road cut you see
in the upper left
picture
Toward the tallest
mountain you see in
the background of the
picture to the upper
right
In the composite
picture this area of
beautiful lights is LA
at night
In the lower right
corner of the picture
is the observatory
I don't know if this will help on
any of the questions. I made a
composite of some pictures and
the Google map of the are.  You
will want to enlarge this picture so
you can see the points I have
marked. Below I have taken just
the Google and added some
comments.
