An internet image search brings up some pictures of the fence and it's relationship to the UP/Amtrak railroad tracks and its eastward end (lower left in picture 3).

Holy Smoke - the 3rd picture - what/where is that? Is that a drop off in front of those people - a trail or what? Is that Mexico to the left and NM to the right where the tracks are?

I wouldn’t care how bad things were where I lived if I had to face a trail like that...No way!!
