The bones of a coyote that died of injury or age while seeking succor on the warmth of a geyser cone lie in a pool of supersaturated mineral water that is refreshed with each eruption of the geyser, Fuller explains. "The bones provided armatures on which, in the course of years, siliceous sinter was deposited to form an ever thicker encrustation. Mineral deposits eventually closed over the watery window where the bones lay." Photo by Steven Fuller
