'''Judith Ellen Fierstein''' is research geologist employed by the U.S. Geological Survey (USGS) at the California Volcano Observatory. Fierstein has published widely on volcanism in Chile and the U.S. state of Alaska, among other regions, including the eruptive histories of Laguna del Maule in the Chilean Andes and Novarupta in Katmai National Park. She is a fellow of the Geological Society of America (GSA), and, alongside research partner Wes Hildreth, won the organization's Florence Bascom Award in 2019.
== Education and career == Judith Ellen Fierstein attended the University of California, Santa Cruz,<ref name=":0" /> from which she received a Bachelor of Science degree in 1980 and a Master of Science degree in 1989.<ref>{{Cite journal |date=Fall 2011 |title=Alumni notes |url=https://eps.ucsc.edu/news-events/dept-newsletters/newsletter-2011.pdf |journal=Earth and Planetary Sciences at UC Santa Cruz |type=Department newsletter |publisher=UC Santa Cruz |pages=14–30}}</ref>
Fierstein first began working for the U.S. Geological Survey in 1980, after attaining her undergraduate degree. She was hired as a summer field assistant to Wes Hildreth for his planned geologic mapping of Mount Adams in the Cascade Range of Washington, but ashfall from the 1980 eruption of Mount St. Helens left their target inaccessible. Instead, the duo backpacked in the Valley of Ten Thousand Smokes within Katmai National Park & Preserve, Alaska, to conduct fieldwork and map Novarupta and surrounding volcanoes. From then until his death in 2025,<ref>{{Cite web |last=California Volcano Observatory|author-link=California Volcano Observatory|last2=Bacon|first2=Charlie|last3=Calvert|first3=Andy|last4=Fierstein|first4=Judy|last5=Hurwitz|first5=Shaul|last6=Lowenstern|first6=Jake|last7=Sisson|first7=Tom|last8=Mahood|first8=Gail|last9=Wilson|first9=Colin|date=July 8, 2025|title=In Memoriam: Wes Hildreth, 1938-2025|url=https://www.usgs.gov/observatories/calvo/news/memoriam-wes-hildreth-1938-2025|access-date=2025-07-12|publisher=U.S. Geological Survey|language=en}}</ref> Hildreth was a mentor to Fierstein and her most prolific research partner.<ref name=":0" /><ref name=":1">{{Cite journal |last1=Hults |first1=Chad P. |last2=Fierstein |first2=Judy |date=September 2016 |title=Katmai National Park and Preserve and Alagnak Wild River: Geologic Resources Inventory report |url=https://irma.nps.gov/DataStore/Reference/Profile/2235401 |journal=Natural Resource Reports |publisher=National Park Service|bibcode=2016nrr..reptE...1H }}</ref>
In a 2023 series of articles in ''Discover'' magazine, Fierstein was named as an influential figure among women in volcanology. She has mentored other successful women volcanologists; for example, Michelle Coombs, former scientist-in-charge of the Alaska Volcano Observatory, was a field assistant to Fierstein while in college. Coombs was also mentored by Terry Keith, one of Fierstein's collaborators on research in Alaska.<ref name=":2">{{Cite web |last=Klemetti |first=Erik |date=Mar 27, 2023 |title=The changing face of volcanology |url=https://www.discovermagazine.com/planet-earth/the-changing-face-of-volcanology |access-date=2025-05-03 |website=Discover Magazine |language=en}}</ref><ref>{{Cite web |last=Klemetti |first=Erik |date=Mar 29, 2023 |title=A long way still to go to create representative volcanology |url=https://www.discovermagazine.com/planet-earth/a-long-way-still-to-go-to-create-representative-volcanology |access-date=2025-05-03 |website=Discover Magazine |language=en}}</ref>

=== Alaska === Following her 1980 graduation from UC Santa Cruz, Fierstein experienced her first-ever backpacking trip while working as a field assistant to Wes Hildreth as they conducted research in Katmai National Park & Preserve.<ref name=":0" /> This was her first time in the park, but she continued to publish articles on its geologic features, including the Valley of Ten Thousand Smokes and the volcano Novarupta.<ref name=":1" /> For example, in 1984, the Alaska Historical Society published an article by Fierstein on the Valley of Ten Thousand Smokes; it was later cited in a symposium on the effects of natural hazards on communities in Alaska.<ref>{{Cite book |last1=Zimmerman |first1=Christian E. |title=Mitigating Impacts of Natural Hazards on Fishery Ecosystems |last2=Neal |first2=Christina A. |author-link2=Christina Neal |last3=Haeussler |first3=Peter J. |date=2008 |publisher=American Fisheries Society |isbn=978-1-934874-01-1 |editor-last=McLaughlin |editor-first=Katherine D. |series=AFS Symposium |volume=64 |pages=375–388 |chapter=Natural hazards, fish habitat, and fishing communities in Alaska |doi=10.47886/9781934874011.ch29 |chapter-url=https://www.researchgate.net/publication/235348806}}</ref> Fierstein continued to research the region and coauthor publications with Hildreth on its volcanic history.<ref>{{Cite web |last=Rozell |first=Ned |date=June 1, 2012 |title=Alaska's Novarupta volcanic eruption remembered 100 years later |url=https://www.adn.com/science/article/alaskas-novarupta-volcanic-eruption-remembered-100-years-later/2012/06/02/ |access-date=2025-05-03 |website=Anchorage Daily News}}</ref>
