This is the view looking back, a few minutes after leaving the last
standing tower. You can barely make out the straight line of the
tracks from the first US tower to the first standing tower. It's
in the middle of the picture. That's some distance to cover!
The Sierra del Carmen mountains are to the left. Boquillas , Mexico
is to the right, but it's out of view. That landing strip looking thing off in the distance is in Mexico.
I'm sure we're looking dead into the Puerto Rico Mine, the source
of the ore for the tramway, but I have no idea exactly where it is.
Another research topic?
