GOSA Presentation Series - Observational and Statistical Analysis of Beehive Geyser’s 2024 Activity
2025-03-04 19:00 - 20:00 (America/Denver) | YouTube Live
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.

GOSA Presentation Series - Geyser Paleontology - Sinter Morphologies and its application to dormant/extinct features
2025-03-11 19:00 - 20:00
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.

GOSA Presentation Series - Sawmill Dormancy: A GIS Perspective
2025-03-18 19:00 - 20:00
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.

GOSA Presentation Series - Fountain Stall Mode Intervals: History and What to Watch For
2025-03-25 19:00 - 20:00
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.

GOSA Presentation Series - The 2024 Activity of Opal Pool
2025-04-01 19:00 - 20:00
Opal Pool is an extraordinarily rare geyser in the Midway Geyser Basin. During the summer season of 2024, it had its 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 its 2024 activity, including footage of some of the eruptions.

2026 GOSA Presentation Series - Eruptions By Proxy
2026-03-17 19:00 - 21:00
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.

2026 GOSA Presentation Series - A Deep Dive of Post Dormancy Sawmill Group Activity
2026-03-24 19:00 - 20:00
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.

2026 GOSA Presentation Series - Introduction to Giant Hot Periods
2026-03-31 19:00 - 20:00
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.
