My eyes scan the geyser basin, pondering the vapors being belched from somewhere deep below. In winter the steam is abundant, clinging to trees and boardwalks, coating animals and plants in ice, making trails slippery. The mists move down-valley on the back of invisible currents, obscuring and revealing. A billowing plume rises over every thermal feature.
My ears sharpen, picking up odd sounds that seem out of context. The small geyser bubbling between eruptions sounds just like a pot of eggs boiling rapidly on the stove. I hear Beehive, a dramatic cone geyser, before I see her, roaring like a firehose at full blast, sending spray 175 feet in the air for minutes at a time. I ski pass Grotto Geyser, with multiple cave-like openings, Middle-Earth-like; some frightful leviathan occupies its depths, whump-whumping as it thrashes. Ga-WHOOMP goes its tail, which is probably not a tail but a reservoir of super-heated water remaining under great pressure. At least that’s what my brain tells me; my neck hairs know differently.
My nose, accustomed to the pure clear air here, catches whiffs of “rotten egg” smell at some pools. Underground deposits of sulfur are plentiful, acidifying some thermal features, helping create mudpots.
My face tingles in the crisp air as I ski, and when a steam cloud envelops me on the boardwalk I can feel the temperature jump for a few seconds. It is no wonder the bison hang around these warm spots in winter.
Taste? A tiny feast — fresh snowflakes on my tongue!
