A friend of mine told me today that 60 Minutes ran an episode on Sunday about a gap in the border wall near Jacumba Hot Springs. Here's what it looked like:
The implicit question from the 60 Minutes piece is, why can't the government fill this four-foot gap "between the 30-foot steel border fence and rock"? How much can it cost to fill up four feet?
By an odd coincidence, I can explain. Four years ago I drove down to the border to take pictures at sunrise, and I noticed that very gap. It attracted my attention because it made the whole fence seem kind of pointless. To see why, here's the picture I took in 2020. It shows a wider view than 60 Minutes did:
As you can see, it's not a four-foot gap between "fence and rock." The fence stops where this hill starts. There's no fence over the entire hill, and it's pretty obvious that climbing up and down that hill would be easy even if the fence were extended. The only way to close it off is to complete the fence all the way up and over the hill.
Why haven't they done that? Beats me, but I assume that building the fence across steep, rocky terrain is challenging in some non-obvious way.
There are lots of rocky hills like this along the border, some them considerably bigger than this one—but still accessible to anyone willing to do a bit of climbing. With enough money I suppose you could still build a fence over any obstacle along the border, but it wouldn't be easy.
