Subject category Comment text
Deposit THREE PROMINANT ULEXITE-TUFA CONES OCCUR ON UPSTREAM SIDE OF THE DEPOSIT. SPRING ACTIVITY WAS STILL PRESENT IN 1955. A SERIES OF GEYSERS AND HOT SPRINGS ARE ALIGNED N-S WITH SIZE INCREASING THE THE NORTH. THE LARGEST CONES ARE 6 M THIGH WITH AN AVERAGE BASAL DIAMETER OF 8 M. IN THE MID-1980'S, ONLY GASES WERE BEING VENTED, ALTHOUGH MUESSIG (1966) REPORTED THAT ONE OF THE GEYSERS SPOUTED COLD WATER AND LOCAL SOURCES CLAIM THAT THE WATER WAS HOT UNTIL 1924. THE B-BEARING WATERS FROM THE SPRINGS AND GEYSERS HAVE FORMED A LARGE ULEXITE DEPOSIT ON THE FLOOR OF THE GULCH CONSISTING OF A TABULAR BLANKET OF HARD HIGH-QUALITY ULEXITE SATURATED WITH WATER. THE BLANKET OF UELXITE IS 400 M LONG, 40-60 M WIDE, WITH A MEDIAN THICKNESS OF 0.4 M. ULEXITE ALSO OCCURS DISSEMINATED IN VEINS IN TERTIARY SEDIMENTS AROUND THE GULCH.
