Yellowstone Geysers Known Active in 1990

T. Scott Bryan


Report on Geyser Observations, 3-18 August, 1990

Ralph C. Jr. and Brenda K. Taylor

ABSTRACT: This report describes the results of the authors' thermal observations from 3 August 1990 through 18 August 1990. The observations were made in Upper Geyser Basin, primarily on Geyser Hill and in Biscuit Basin, and at Norris Geyser Basin.


The "Big Cub-Lioness-Beehive" Connection

Rocco Paperiello

ABSTRACT: Recent discoveries have added much to the known activity record of Big Cub and Lioness Geysers, and have revealed an apparent activity relationship between them and Beehive Geyser.


"Mugwump" How and why the name was applied to Three Crater Geyser, Three Sisters Springs, Upper Geyser Basin, Yellowstone National Park

Lee H. Whittlesey

ABSTRACT: The curious name "Mugwump" was applied to a geyser of the Three Sisters Springs. The history behind the name is described, and an attempt to identify the modem spring is made.


Major Geyser Activity in the Round Spring Group, Upper Geyser Basin, Yellowstone National Park, May 25-26, 1990

T. Scott Bryan

ABSTRACT: Round Spring, a member of the Round Spring Group of Yellowstone's Upper Geyser Basin, underwent an unusual phase of eruptive activity on May 25-26, 1990. Details are recorded in this paper.


Notes on Fluctuations in the Runoff from Spiteful Geyser, Upper Geyser Basin, Yellowstone National Park

Tania Vincent and David Scheel

ABSTRACT: This article expresses the speculation that a careful monitoring of the volume of Spiteful Geyser's runoff into Fan Geyser might provide a clue to the timing of Fan and Mortar's major eruptions.


Jewel Geyser Update 1990

Ralph C. and Brenda K. Taylor

ABSTRACT: This report describes the authors' observations of Jewel Geyser in August, 1990 and May, 1991. Ninety five closed intervals over a total of twelve hours in 1990 and one hour in May, 1991 are included in the data. A mathematical model relating the ob- served number of bursts in an eruption to the subsequent interval described in a previous paper is updated with 1990 observations. The interval to the next eruption is predicted within 2 minutes by adding 4m25s plus lm5s for each observed burst in an eruption.


Whistle Geyser, Black Sand Basin, Yellowstone National Park Observations of July 18, 1991

Clark Murray

ABSTRACT: Eruptions by Yellowstone's Whistle Geyser have been very rare. The author witnessed an eruption from near its beginning and found the activity to be quite different from that of most previously published descriptions.


Activity of the Fountain Geyser complex [1990], Yellowstone National Park, Wyoming

Gordon Bower

ABSTRACT: The Fountain Geyser Complex, including a minimum of eleven geysers, is located near Fountain Paint Pots, fourteen kilometers north of the Upper Geyser Basin. This paper discusses some aspects of the activity of the complex during the summer of 1990.


1991 Activity of Morning Geyser and Other Features in the Fountain Complex [Lower Geyser Basin, Yellowstone National Park], Part I, May 4 and 5, 1991

Lynn Stephens

ABSTRACT: After eight year's of dormancy, Morning Geyser reactivated during the 1991 season. There were three observed periods of activity-- one on May 4 and 5 with five known solo eruptions of Morning, one on July 4 and 5 with two concerted eruptions of Fountain and Morning, and one from August 9-29 that started with a concerted eruption of Fountain and Morning, was followed by 118 known solo eruptions of Morning, and concluded with two concerted eruptions of Fountain and Morning. This report describes the activity of Morning Geyser and other features in the Fountain Complex on May 4 and 5, 1991. (July and August activity are described in other reports.)


1991 Activity of Morning Geyser, Part II, July 4-7, 1991

Lynn Stephens

ABSTRACT: Morning and Fountain geysers erupted in concert on July 4 and again on July 5, 1991. This report describes activity of geysers in the Fountain Complex for July 4 through 7, and compares the activity patterns during this time with those observed during the May 4 and 5, 1991, activity of Morning.


1991 Activity of Morning Geyser, Part III, August 9-29, 1991

Lynn Stephens

ABSTRACT: The activity of Morning on May 4 and 5 and July 4 and 5, 1991, (discussed in separate reports) was just a prelude to its activity in August 1991, when Morning had three concerted eruptions with Fountain and 118 verifiable solo eruptions. This report summarizes Morning's activity during the period August 9-29, 1991, and the impact Morning had on other geysers in the Fountain Complex.


Pinto Geyser in History: Its "Arsenic", "Twentieth Century", and "Fireball" Alter Egos

Lee H. Whittlesey

ABSTRACT: An analysis of historical records indicates that the feature now known as Pinto Geyser is the same as that previously known as Arsenic Geyser, Twentieth Century Geyser, and Fireball Geyser. This confusing history is explained.


Will the Real Arsenic Geyser Please Stand Up?

Rocco Paperiello

ABSTRACT: The identity of Arsenic Geyser has been confused throughout Yellowstone Park history , and the names Fan, Fireball, Twentieth Century , and Pinto have all apparently been applied to the same feature. This history is clarified.


Eruptive Activity by Black Pool, August 15, 1991, West Thumb Geyser Basin, Yellowstone National Park

Allan Friedman

ABSTRACT: Black Pool had never been known to erupt prior to August 15, 1991. After a month or so of gradual heating, an apparent steam explosion led into a short series of eruptions, which concluded on the same date.


Notes on Buried Geyser, Lone Star Geyser Basin, Yellowstone National Park, Wyoming

Gordon R. Bower

ABSTRACT: Buried Geyser, a significant but little-known feature near Lone Star Geyser, was visited on two occasions during the 1990 season. This paper is a discussion of the eruption types and patterns that were observed.


Observations at Shoshone Geyser Basin, July 17-18, 1991

Jeff Cross

ABSTRACT: In narrative form, observations conducted at the Shoshone Geyser Basin are summarized. Explanatory comments have been added by the editor of the Transactions.


Hot Springs of the Central Part of the Shoshone Geyser Basin, Yellowstone National Park

Rocco Paperiello

ABSTRACT: A detailed set of tables and maps make up an inventory of the hot springs and geysers of the central portion of the Shoshone geyser Basin. An historical review of Union Geyser is presented. Finally, information concerning the current activity and the identity of Lion Geyser along with a nearby "new" geyser is presented.


On the Modern Identity of Three Historic Hot spring Names, Heart Lake Geyser Basin, Yellowstone National Park

T. Scott Bryan

ABSTRACT: Modern authors have attempted to correlate Comstock's [1873] Puffing Spring, Sand Spring and Hissing Spring with modem features within the Fissure Group of the Heart Lake Geyser Basin. I believe these correlations to be incorrect, and that a more careful analysis of Comstock's admittedly brief description of these features places them within the Upper Group of the Heart Lake Geyser Basin.


A Brief Update about United States Geyser Localities other than Yellowstone National Park and Umnak Island, Alaska

T. Scott Bryan

ABSTRACT: The status of geyser activity in the other localities of the United States, other than Yellowstone and Umnak, is poor.


Geyser Activity on the Beowawe Terrace, Beowawe, Nevada: An Historical and 1980s Summary

T. Scott Bryan

ABSTRACT: By comparing maps and descriptions of the hot springs and geysers on the main terrace at Beowawe, Nevada as they were during the 1940s and 1950s, an attempt has been made to correlate those features with the observed eruptive activity of the 1980s, which activity is also described.


The Geysers of Umnak Island, Alaska

T. Scott Bryan and S.A. Liss

ABSTRACT: Geologists with the Alaska Division of Geological and Geophysical Surveys have recently completed a study of the geysers and other hot springs along Geyser Creek, near Geyser Bight, on Umnak Island. Although the total number of enumerated springs is small, at least 12 active geysers have been observed during the years since 1947, making Geyser Bight among the most significant geyser fields in the world.


A Bibliography of the Geysers of the world, excluding the United States

Geyser Eruption Angle, Form, and Frequency as a Function of Geyser Age

T. Scott Bryan

ABSTRACT: A comparison of the geysers within Dolina Geizerov on the Kamchatka Peninsula of Russia with those in Yellowstone National Park, New Zealand, Iceland, and El Tatio indicates that the angle at which geyser water is erupted and the type of eruption both are functions of how old the geyser is. In each case, the eruption form and attitude is controlled by surface and near-surface geyserite deposits whose development causes evolutionary changes in the geyser performance. In similar fashion, the frequency of a geyser's eruptions can be related to the degree of system "self-sealing", which is again a function of mineral deposition with time.


Annual Basin-Wide Disturbances Along the Firehole River: A Very Speculative Thought

T. Scott Bryan

ABSTRACT: Annual "basin-wide disturbances" are well documented for the Norris Geyser Basin, but have generally received only passing discussion as a possibility in other areas of Yellowstone and elsewhere. However, a long-standing rule of thumb has been that the late summer season is the time most likely to see rare unpredictable eruptions and large-scale changes in Yellowstone geyser basins other than Norris. Perhaps this is because of a similar effect. Observations during August, 1986 provide evidence for such a disturbance within the geyser basins along the Firehole River.
