Geyser Photography

March, 10th – Replay available below

Presenter: Ryan R. Maurer

Photography is both a public engagement tool and a scientific record. A well-composed image of a geyser eruption can capture its drama and beauty while simultaneously documenting technical and historical data — giving the public a reason to care and scientists a reason to trust. In this talk, I’ll draw on historical photographs and my own archives to show how a single image can achieve both goals. By: Ryan Maurer

Eruptions By Proxy

March 17th – Replace available below

Presenter: Korben Cooper

Discover how modern tools and data science enable remote observation and analysis of geyser behavior. This webinar serves as a guide through webcam use and performing basic data analysis.

A Deep Dive of Post Dormancy Sawmill Group Activity

March 24th – 7:00pm MDT

Presenter: Caleb Dye

This presentation dives into the basics of the Sawmill group and its cyclical activity, variations on the usual cycles, long term-activity changes, eruptions of Penta and their setup, and finally the rare behaviors I have observed over the past year and a half.

Introduction to Giant Hot Periods

March 31st, 7:00pm MDT
Presenter: Tara Cross

Introduction to cycles of the Giant-Grotto complex with descriptions of Giant Hot Periods and discussion of timing of other members the group and what to look for when an eruption of Giant is imminent.

Observational and Statistical Analysis of Beehive Geyser’s 2024 Activity


Presenter: Korben Cooper

This presentation explores the eruptive and behavioral observations of Beehive Geyser during 2024, providing statistical and observational insight into key factors, including interval, duration, indicator activity, progression into eruptions, impact of external conditions, and correlations with nearby geysers.

Geyser Paleontology – Sinter Morphologies and its application to dormant/extinct features

Presenter: Micah Kipple

Geyserite and its associated structures are as striking and unique as the fountains that create them. This presentation will summarize some of the more common morphologies of geyserite and sinter in Yellowstone geysers, the behavior that produces them, and how that can be used to reconstruct hypothetical prehistoric behavior of dormant features, and interpret current formations to glimpse into the past.

Sawmill Dormancy: A GIS Perspective

Presenter: Craig Munson Jr

This presentation will go over GIS maps generated with eruption data and basic correlations displayed in a pleasing way. These maps provide insight into theoretical connections of the Sawmill group before, during, and after the 2017 Sawmill dormancy. Methods of how these correlations were calculated and plotted on a map will also be shared. Strengths and weaknesses of utilizing these methods and correlations will also be discussed.

Fountain Stall Mode Intervals: History and What to Watch For

Presenter: Tara Cross

This presentation will address the historical background of “stall” intervals at Fountain Geyser and answer questions regarding the behavior of the major members of the Fountain Group during these events.

The 2024 Activity of Opal Pool

Presenter: Ben Vander Ley

Opal Pool is an extraordinarily rare geyser in the Midway Geyser Basin. During the summer season of 2024, it had it’s first known eruptions in ten years. This presentation will discuss the historically known periods of activity, the characteristics of an eruption of Opal Pool, and the observations made during it’s 2024 activity, including footage of some of the eruptions.

Go to 5: All About Two Way Radios

Presenter: Art Haeussler

Yellowstone’s remoteness and topography presents unique challenges in todays always connected world. Two way radio technology is still the most reliable form of communication throughout the Greater Yellowstone area. We will cover the basics from big box store two way radios and how to program them to more advanced GMRS/FRS radios. Learn about licensing requirements, gear recomendations and tips/tricks on how to operate your radios effecively.

Introduction to Giant

Presenter: Tara Cross

Overview of historical active phases, related features in the Giant-Grotto system, and when to look for Giant Hot Periods.

When To Walk Away – A New Look Into Old Data

Presenter: Demetri Stoumbos

Geyser interval statistics have long been a useful tool for gazers, primarily seen as a histogram and an average. Here we will look at a different way to crunch the numbers and tease out some trends that lie hidden in how we’re used to seeing the data.

Geyser Gazing in New Zealand


Presenters: Suzanne Strasser and Heinrich Koenig

Geyser gazing in New Zealand is a different experience than Yellowstone: a combination of the familiar and the different. Suzanne Strasser and Heinrich Koenig will present a perspective based on their two recent visits. They will discuss the thermal areas they visited, how they maximized their observation time and opportunities, what they would do again and what they would do differently on their next visit. Information on reference materials and maps will be provided.

The power of continuous, long-term hydrothermal monitoring

Presenters: Mara Reed

Norris Geyser Basin is the only thermal area in Yellowstone with permanent monitoring equipment that telemeters data for storage in public databases. Mara Reed, PhD candidate at UC Berkeley, will share insights from ongoing research on Steamboat Geyser and Norris disturbances that highlight the necessity of long-term monitoring.

Compiling The Maximum Known Height of The Major Geysers

Presenter: Ben Vander Ley

Establishing some standards for measuring geyser height, and compiling a list of the record known height for many of the major geysers. Also will be giving some additional information related to the height of each geyser covered.

GeyserTimes: A History and Future


Presenter: Jake Young

How GeyserTimes started, major events, counts of historical data, etc.

Steam and Sage – An Overview and Visitor’s Guide to Mickey Hot Springs

Presenter: Micah Kipple

Economic Activity January 2024 and Penta Mixed Phase

Presenter: Graham Meech

Description of the rare Economic activity seen in January with videos of minor, normal, and major eruptions, and suggestions of what to look for this summer. Also includes advice on when to look for Penta Mixed Phase eruptions which were quite common last year.
