There should be more than one cone though. And the material that this one is made of is different than what you find flowing from a volcano.
True.
Limestone and chip.
It may be a gas breakout.
They do have that permaburning natural gas seep over there too.
And it may be a result of a nuke capping procedure as someone else mentioned.
But it was discovered in 1949.
So that doesn’t fit.
It being a natural gas seep cone, that would explain people dying near it.
Hmm.
Wonder if they could do seismic tomography near there to get a view of what’s below?
