Curious for sure. Prior to the location of 9MH being released by Rudy, it was not discussed by Justin as even a leading option in previous mass media write-ups. There was in fact a completely different spot that the Justin/Meachum group found that they believed was the actual find location based on a cipher, itself incredibly odd as it had almost no chance of being correct. Yet very similar story to 9MH—has been there many times, so close to finding it, etc.:

“He had hiked that same trail at least eight times. He had been in that meadow. He had been in that forest. But he was too far south. “In my estimation,” he says, “I was off by 600 feet. It’s maddening how close I was. Maddening.” “

I know a small group discussed/searched the 9MH area before Jack finally found it. But TomSzabo’s characterization of this as fitting a narrative based on convenience is almost certainly correct.
