Chief Geologist Frank Bradley and party, a group of the 1872 Hayden Expedition, named Shoshone lake and geyser basin. However, Osborne Russell, an early explorer and trapper, may have been the first European to enter the basin in 1839.

Shoshone Geyser Basin, located at the west end of Shoshone Lake, requires an 8.5 mile hike from Lone Star Geyser or a canoe trip across Lewis and Shoshone lakes to reach these jewel-like thermal features. This geyser basin is truly pristine. Because of its remote location one can enter this basin and find little evidence of man. The pools and geysers still retain most of their original formations of intricate sinter. No boardwalks exist in the basin and caution should be exercised while exploring, since one pool has already claimed the life of a man in 1988.

This small basin contains an estimated 110 thermal features. Union Geyser is the famous feature in the basin. It was active during the early 1900s, but it has had long periods of dormancy and has been dormant since the mid 1970s. The three small mounds, standing three feet tall, show little activity. Minute Man Geyser is now the main attraction at Shoshone. It is a regular spouter with intervals of one to three minutes.


SOAP KETTLE 0
Temperature 197°F Interval 9-21 minutes. Duration 1-3 minutes. Height 4-6 feet. This geyser has a distinctive large crater. Golden sinter beads line the vent of the four-feet-high cone. It has regular geyser activity, and an eruption is easy to see. An eruption begins with water rising in the vent and crater. As water begins to overflow and boil splashing begins and triggers an eruption. Most of the activity is splashing but there are bursts which reach six feet. After an eruption, the crater drains and slowly refills with boiling water for the next eruption.

GOURD SPRING 0
Temperature 196°F Interval minutes to hours (irregular).
Duration 15-60 minutes. Height 2-5 feet. An elaborate,
massive basin has been built of sinter by the continuous splashing of water. The crater, lined with white, beaded sinter and a golden-colored inside rim, measures ten feet long by eight feet wide. The water constantly boils and has occasional eruptions. The eruptions are minor and usually consist of continuous splashing. The activity of Gourd is cyclic. Because corresponding changes in water level are apparent, there may be a connection with nearby Shield Geyser.


MINUTE MAN GEYSER 0
Temperature 180°F Interval 1-3 minutes. Duration 2-10
seconds. Height 10-40 feet. Professor Frank Bradley, Chief
Geologist of the Hayden Expedition in 1872, named Minute Man because it erupted nearly every minute. It has a large cone five feet high by 12 feet long built of gray sinter or geyserite. Before an eruption the vent and crater fill with water. Boiling triggers a violent eruption as water jets to 10-20 feet high at first, but declines in force until the water and steam are exhausted. A series of these eruptions will occur for several hours and then the geyser enters a quiet period for another few hours until the cycle is repeated.


TAURUS GEYSER 0
Temperature 196°F Dimensions 8.5 feet diameter. Depth 27
feet. Taurus Geyser is a deep blue pool. Orange-colored
cyanobacteria and algae line the edge in contrast with the dark blue water. The spring is in a constant state of ebullition. It has erupted in the past, but only during an eruption of nearby Union Geyser, the largest geyser in the basin which itself has long periods of dormancy. Taurus has erupted with bursts up to four feet high, but mostly this geyser boils and splashes.


KNOBBY GEYSER 0
Temperature 192°F Dimensions 11x13 feet. Depth 6 feet. Knobby Geyser is a small, spring-like geyser in the North Group. It has a white shallow pool, square shape, with an intricate sinter or geyserite border. The ornate rim is composed of white and gray, rosette-like clusters. Knobby has cyclic eruptions depending on the activity of nearby Velvet Spring, which has periods of long dormancy. The eruptive activity will last from one to three hours with occasional pauses varying in length. The duration and volume of each eruption have direct effect on the length of the pause. The eruptions can reach 10-25 feet high.


NORTH GROUP 0
Temperature 189-199°F This group has the largest collection of small springs in the basin. Some of the major thermal features are Glen Spring, Funnel Spring, Yellow Sponge, Knobby Geyser, Bead Geyser, Velvet Spring and Bronze Geyser. All are alkaline springs and have colorful basins and run-off channels. Some features are stained red and orange by iron oxides, and others green, yellow or brown by cyanobacteria and algae. Intricate sinter borders have formed around many of the springs. All the thermal features have high temperatures, and boil constantly.
