Valley of Death
Not to be confused with “Death Valley,” this Russian peninsula is just as dangerous, but significantly farther away. The Russian Valley of Death falls much farther north than America’s Death Valley, and its threat doesn’t come from its harsh climate, it comes from its high concentration of toxic fumes. The poisonous fumes come from unsettled volcanos and geysers that surround the valley. Very few deaths occur here annually, but hikers regularly have to evacuate the area when there is a gas bleed, which causes people to feel nauseous, dizzy, feverish, and in some cases, internal bleeding.
