A good bi of this thread seems like a pocket of gas.
Nope as gas does not accumulate on open trails on top of mountains that are not volcanic. However if gas was the culprit their would still be gas in the lungs and in lung tissue. The fact is that the authorities know what killed these people and are not being allowed to say. Thus terrorism is indicated
We deserve the truth, not lies or in this case no answer. If no one knows what killed these people all of Yosemite should be closed including rangers evacuated, if this has not happened then the cause of death is clear and they are not disclosing it to us
I VOTED FOR TRUMP TWICE, AND WILL VOTE FOR HIM AGAIN
