Deposit THE MAIN CONE IS PERFECTLY PRESERVED AND HAS A DRY VENT. SECONDARY VENTS ARE LOCATED A FEW METERS BELOW THE MAIN VENT. AT THE FOOT OF THIS GEYSER, THERE IS A SLOW LEAKING OF FERRUGINOUS SALINE WATER WITH A MINOR VENTING OF CO2. THE TRAVERTINE FORMING THE CONE IS YELLOW-GRAY, POROUS, AND LIMONITIC WITH A FEW LENSES OF ONYX. THE ULEXITE IS VERY PURE, WHITE, SILKY, AND HARD AND HAS A MAXIMUM THICKNESS OF 50 CM. SIMILAR, BUT SMALLER, DEPOSITS OCCUR IN THE VICINITY OF THE MAIN GEYSER, THE LARGEST AT THE EXTREME S END OF THE GULCH. FOUR OTHER B-BEARING AND ONE NON-B-BEARING GEYSERS ARE ALIGNED ALONG THE SAME SIDE OF THE RIVER. ANOTHER 8 SPRING DEPOSITS ARE NEAR THE MAIN GEYSER; 1 TO THE WEST OF THE MAIN GEYSER AND 7 IN TWO SMALL GULLIES TO THE EAST.
