Geological horror. You find a geode and crack it open and the crystal lining its walls is human blood that can't be genetically matched to anyone. You find a human skeleton but every one of the bones is made from rock, a rock that you know can't be whittled into those shapes. You find layers of clay and loam that sport ancient fossils at the top and the still-rotting corpses of modern animals at the bottom.
This reminds me of the blood river in Antarctica. For like a century scientists had no clue why this river looked like, acted like, and felt exactly like blood. Turns out itβs just really high in iron.
"Blood River in Antartica" yeah right there's no way a river looks like bl-
...nevermind
Blood Falls isn't just high in iron, it's the byproducts of extremophile bacteria that have been isolated under a glacier in a iron- and sulfur-rich anoxic brine for the past 5 million years.
