Reply to comment by SnekkyGlekky in Will a 400m long tube have breathable oxygen inside? by SnekkyGlekky

If there was rotting material in there, maybe it would build up a bit. But, if it's open and going through a hill you'll probably get a decent amount of airflow through it.

Cool, I was wondering if the air wouldn’t be able to penetrate the tube because of how long it is

Depends on the pressure and temperature differential. You could have a face of the mountain be in direct sun heating up wand creating a difference in pressure. It's not about how windy it is, the pressure delta is what makes wind

No, the length of the tube might slow the wind down, but it should still move air through the tube. I assume you are thinking of crawling through the tube. I would certainly take precautions before attempting such a thing. Perhaps search for spelunking resources that can tell you what equipment to take, what procedures to follow, etc.
