Celebrate 50 years of RMBL river studies and the Benthettes!
August 21 – 24, 2026 in Gothic, Colorado
Freshwater Forum 50 & Benthette Reunion 2026!
Please join us for Freshwater Forum 50 & the Benthette Reunion 2026 at the Rocky Mountain Biological Laboratory in Gothic, Colorado, from August 21–24, 2026.
About the Benthettes
The lineage of “Benthettes” reflects the broader RMBL culture, shaped by researchers who combine scientific rigor with a deep care for place and community. It embodies a way of doing science grounded in relationship and responsibility (Voices of RMBL: Kara Cromwell). Peckarsky’s team studying the benthos—Greek for watery bottom-dwellers—was affectionately known as “The Sensuous Benthettes.” Over the past 50 years, generations of Benthettes have advanced stream ecology while fostering mentorship, collaboration, and lasting friendships. For many, living and working in Gothic as a Benthette was both creatively challenging and deeply formative, an introduction not only to the demands of field research, but also to what it means to be part of a collective dedicated to science and to one another (Alumni Stories: Tracy Smith).
Freshwater Forum 50 & Benthette Reunion
The Benthette Reunion celebrates 50 years of river studies and marks the launch of Rocky Mountain Rivers, a new nonprofit supporting the next 50 years of river science (read the Science Story published in the April 2021 RMBL newsletter). The reunion aims to honor the legacy of Benthettes, share knowledge across generations, and inspire continued engagement with RMBL and river research. The weekend will reconnect alumni and strengthen the RMBL community through a mix of all-community gatherings and optional activities.
Key features of the Freshwater Forum 50 & Benthette Reunion include:
- Happy hour and campfire
- Participatory talks on 50 years of stream ecology
- billy barr’s slideshow Gothic in Winter
- Storytelling sessions
- Hikes to long-term research sites
- T-shirt design contest
- revival of the No Talent Show—“Benthettes’ Greatest Hits.”

Benthette Reunion T-shirt Design Contest
As a Benthette, you know just how iconic Bobbi’s T-shirt collection is; and how legendary Benthette T-shirts have been over the decades. From the “Waiting with Baetis Breath” tee, the classic “Benthos” tee, the “Mayfly Chorus Line”, “Dead Mayfly Society”, and “Team Egg”
These designs have become part of our shared history.
As we celebrate 50 years of community, we want to revive this tradition with a Benthette T-shirt created for the reunion and beyond. Have a design, slogan, or idea? We want to see it! You don’t have to be attending the Reunion to submit a T-shirt design. Upload your designs here.



Share Your Benthette Stories:
From field days to lifelong friendships, Benthette stories span generations. As part of the reunion, we would love it if you shared your most iconic stories and memorable moments from over the years!
We’ll host a story-sharing session at the reunion and are also compiling these reflections into a written collection that captures the people, moments, and experiences that have shaped this community. How did you first connect with RMBL? What memories of being a Benthette stay with you? How has being a Benthette shaped your career and life paths? What do you hope future generations of Benthettes experience at RMBL?
That’s where this form comes in!
Use it to start reminiscing and share one or more moments; silly, serious, wild, or meaningful. We’ll use your responses to begin writing down Benthette stories from across the years in a collection. You don’t need to be attending the reunion to share! Upload your stories here.
Share Your Photos:
Do you have photos from your Benthette days or time at RMBL? We would love to see them!
Please use this form to upload your favorite photos! They will be shared at the reunion and added to our growing story collection and Benthette record, helping preserve the history and spirit of this remarkable community.
Upload photos from your time as a Benthette here.

Margot Buckelew
Margot spent summers 2016 – 2020 as a Benthette throughout her academic career at the University of Wisconsin Madison (undergrad), and Yale School of the Environment (MEM), where she completed her capstone project on the history and significance of in-stream (non-consumptive) water rights in Colorado. She is currently working for the EPA in Washington, DC on water quality grant programs for Tribes.

Kara Cromwell
Kara is a stream ecologist and science communicator who finds inspiration at the intersection of ecology with everyday life. In 2012 she came to RMBL as a PhD student from the University of Wisconsin – Madison and became a Benthette, completing her PhD in 2018. She is currently a Faculty Affiliate at the University of Montana. She founded and is the Executive Director of the non-profit Rocky Mountain Rivers.

Andrea Encalada
Andrea became a Benthette at RMBL in 1999 as a PhD student at Cornell University. After completing her dissertation research in 2004 she moved back home to her native Ecuador where she has been a faculty member and a rock star of international acclaim at the University of San Francisco, in Quito. She recently finished a 5-year term as the Provost of USF and is now settled back into her preferred role as teacher, researcher and mentor.

Matt Fuller
Matt was first introduced to stream ecology as an undergraduate at Cornell University, after which he followed Bobbi to the University of Wisconsin-Madison and RMBL where he became a Benthette and completed his Masters research (2006-2008). He received his PhD at Duke University (2017) and is currently a research scientist with the US Forest Service and adjunct faculty at UMass-Amherst in Amherst, MA.

Havalin Haskell
Havalin is a native of Crested Butte and was introduced to RMBL as a junior scientist in the youth education programs. She became smitten with streams during the RMBL high school class summer 2020, and completed an independent project in summer 2021 to become a full-fledged Benthette. She is a recent graduate of Colorado College pursuing a career communicating science, and is currently the Communications Director of the non-profit Rocky Mountain Rivers.

Bobbi Peckarsky
Bobbi first came to RMBL as a high school teacher in 1974 to take classes. That summer transformed her life and she has come back every summer since, as a PhD student, coursework instructor, mentor and researcher. She “retired” from Cornell University in 2005 and moved back home to Wisconsin where she has continued research and mentoring both at UW and at RMBL. She is the founder and matriarch of the Benthettes and President of the Board of Directors for the non-profit Rocky Mountain Rivers.

Marge Penton
Became a life-long Benthette at RMBL in 1981 as a research assistant for Bobbi at Cornell University after receiving her BS degree at Northern Arizona University as a freshwater biologist and an MS at the University of Arkansas studying diatoms. After leaving Cornell in the late 1980’s, she moved back to her native Arizona to teach high school science. But she has continued spending time in the summers as a Benthette. She is the secretary of the non-profit Rocky Mountain Rivers.

Tracy Smith
Tracy first came to RMBL in 1982 as an undergraduate coursework student. Due to her exuberant personality, tireless work ethic and extraordinary softball acumen, Bobbi hired her in 1983 as a research assistant, which began her illustrious career as a Benthette. After a 9-year hiatus, in 1992 she came back to spend 9 more years as a Benthette. Tracy helped us discover many wonders of stream invertebrate life at RMBL. She recently retired as the Director of Retention through Academic Mentoring at Humboldt State University. She will be organizing the Benthettes’ Greatest Hits at the 2026 Reunion.
