Does that section even exist anymore?
A lot of the old fencing was replaced with that 23-30 foot bollard style with 4 feet of sheet metal at the top to prevent shimming up and over.
That looks like the older 10-12 ft version.
I’m not sure if it still exists I took it off Google images but one thing is for sure. That fence you see attached to the iron columns was tied on in the Mexican side of the border to climb up from.
It’s things like this that need to be taken out when spotted.
