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.

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.
