Nu este un lac natural, mai degraba un lac rezidual, rasarit intr-o veche mina de cupru din Butte, Montana, Statele Unite ale Americii. S-a format la o adancime de 270 de metri, iar apa sa are o aciditate care inca nu a fost egalata pe Terra. Metale grele, substante chimice extrem de periculoase (arsenic, zinc, cadmiu), asta ca sa nu mai vorbim de acidul sulfuric, toate formeaza o „supa” ucigatoare pentru orice forma de viata. Ceea ce este si mai grav este ca nivelul sau creste constant, inca din anul 1982.
Un incident sinistru a avut loc in anul 1995, atunci cand un
stol urias de gaste arctice a aterizat pe apa lacului. Absolut
toate pasarile au murit, cercetatorii reusind sa scoata la
suprafata „numai” 342 de carcase partial dizolvate in acidul
ucigator. La urma urmei, lacul nu este altceva decat o alta „opera
de arta” a omului.
