Or Google search "Fruitland outcrop".
We already know Google actively dodges "denier results" so it's pretty bad when they can't even hide it.

Turns out it's natural and has been off gassing for at least a few million years.

As the believerslike to say:
"It's settled science"

I like how the so called environmentalists just went straight to blaming man's activities with out making any effort to find the cause and were all like "there is a huge methane cloud over NM, we need to do something about it right now, even if it has nothing to do with the methane cloud or finding out the source". (That pretty much sums up the narrative)

You know if you fail to identify a problem there is no chance of fixing it.

Or its man made and some how 3 years later no one has been able to figure out where it's coming from. But, I don't even know how this could still be considered as a possibility.
