(EDITED: thanks!)
More societal awareness of rare-im-nature combos of capsaicin, pressure,heat, please!
The important part is that they're dried so there's not enough water to cause a steam-fueled capsaicin bomb in your microwave.
Looking out for one another in ways like this is mostly just baked into the subculture and that's one reason hiker boxes work (the other being you just don't want to carry extra weight). As someone who has backpacked through Yellowstone, I'm not sure it would work for the tourist culture there.
The fact that there's not a stand/bin with a "need one, take one" type of sign is kind of head scratcher
