Welcome Geosciences friends to the 2020 GEOScape newsletter! I’m sure it’s an understatement for our readers to note that this has been an unusual year as the numerous and unprecedented developments of the COVID-19 pandemic In This Issue affected so many aspects of our personal and professional lives and presented profound challenges to our community, University, and department. 3 Message From the Dean

Following spring break, Colorado State University pivoted to 6 Alumni News become a fully online University through to the end of spring semester. This required extraordinarily rapid, all-hands, and 9 Student Highlights heroic efforts on behalf of our faculty and staff to completely revamp our teaching and essentially all other aspects of our 14 Faculty and Staff department activities. These changes also demanded focus and dedication on behalf of our students, as they were called 30 Departmental News upon to abruptly adapt nearly every aspect of their academic and personal lives to accommodate strange and new 35 Departmental Honors circumstances (as well as become experts in Zoom, Teams, and other virtual teaching and communications platforms). Rick Aster, near Round Mountain 40 Thanks to Our Supporters Summer required yet more exceptional efforts as faculty worked to accommodate summer research and teaching while preparing for a partial in-person, partial online and social-distanced fall semester. One exceptional accomplishment from the summer is that we were one of the few geosciences programs to successfully conduct an in-person summer Field Camp (for our geology seniors, who needed this to complete their degrees this year). This success, again, was made possible by outstanding commitment and effort on behalf of department faculty and staff.

As fall semester began, we were certainly more experienced and confident working remotely and socially distancing our in-person labs and other courses than we had been earlier in the year. However, the challenges of largely or wholly at-home work, especially for colleagues with at-home kids and associated home-school responsibilities, was considerable. CSU made the (especially in the perspective of the national trends, as I write this) prescient decision to have our in-person fall teaching transition to and complete the semester fully online following Thanksgiving break. In a testament to the many laudable efforts by our faculty and staff to adapt our teaching, living, and other efforts across the department, college, and campus, we continued to deliver in-person classes into November, thus far avoiding campus-closing viral outbreaks that have occurred at so many other higher education institutions. Our campus and northern Colorado community was yet further impacted by multiple historically large, prolonged, and rapidly moving forest fires, which were not completely contained until November. Our Mountain Campus experienced a near miss when the enormous (209,000- acre) Cameron Peak Fire swept through, but all of the structures remarkably survived,, thanks to the at times almost unbelievable efforts of our firefighting heroes. This fire ultimately burned down to the foothills and nearly to the doorstep of Fort Collins near Masonville. Yes, we are all indeed, hoping for a (much) more “normal” year in 2021! On the cover Wild Basin is seen from the windy All that said, Geosciences continued to innovate, evolve, and realize new opportunities, even summit of Mount Orton, Rocky Mountain during the exceptional times of 2020. Notable happenings included the promotion of Sara Rathburn to full professor, the arrival of Assistant Professor Jeremy Caves Rugenstein (who is National Park. Photo by Rick Aster enhancing our teaching and research depth in Introductory Geology, Isotope Geochemistry, and Paleoclimatology), and an exciting new collaboration with the Denver Museum of Nature & Science with alumnus and Curator of Dinosaurs Joe Sertich (B.S. ‘04) to expand our GeoScape is the annual newsletter paleontology teaching and other efforts. In staff news, we were pleased to welcome a new produced for alumni and friends of the administrative staff member, Kailarae Lilly, to the department this fall. On the bittersweet side, Department of Geosciences at Colorado our extraordinary and longtime academic success coordinator and all-around department State University. We appreciate your colleague, Jill Putman, will be leaving the department in January 2021 for a new opportunity continued support and welcome your with CSU’s Collaborative for Student Achievement as its associate director for outreach and thoughts. support programs, where she will continue to foster student success across campus. Jill has had a tremendous positive impact on our students and department since she joined us in fall 2014 and leaves big shoes to fill. Patti Uman continues to anchor our department office with her exceptional efforts as lead office administrator. In summary, I applaud and compliment colleagues across the department staff and faculty for their above-and-beyond efforts to sustain our teaching, research, and broader mission as a Geosciences department. I wish all of our readers well as we continue to live through these “interesting” times, and as we look forward to a bright future. As always, I offer a huge end-of-the-year thanks to our generous alumni, friends, and collaborators who do so much to enhance professional opportunities for our students and department activities through teaching, networking, and philanthropy.

Rick Aster, Ph.D. Geosciences Department Head GEOScape Fall 2020 | 2 A Note From Dean John P. Hayes

2020 has been a year like no As always, it is a real treat to read of the accomplishments of other in the history of the planet. the faculty and staff in Geosciences and some of the great On one level we all share a work of the department. Geosciences is a department that just common experience in that the keeps getting better and better. While it is easy to focus on pandemic has impacted every the outputs and outcomes, I want to take a moment to state one of us, but I am deeply aware what is probably obvious: All of the great work being done in that each of us has experienced Geosciences is fueled by the department’s incredible faculty, those impacts in unique and staff, and students. distinct ways.

John P. Hayes Ph.D. Despite the challenges we are facing, this is an exciting time at CSU. This year, under the leadership of President Joyce McConnell, the University has begun an effort to work toward creating a new, courageous vision for the future. This endeavor strives to build on our current strengths, take advantage of our foundation of programs and location, and tap into the innovative thinking of our faculty and staff to position the University to make even greater impacts in the Dean, Warner College of Natural Resources years to come. I anticipate the outcome of this work to align exceptionally well with our programs in Geosciences.

GRI FAREWELLS In 2020, the GRI team said farewell to two of our CSU research associates. John Graham retired on May 8 and Georgia Hybels passed away on May 19.

John Graham (Ph.D., ’96) joined GRI in 2001 as one of our earliest hires and one of the three core report writers. Over his 19 years with the program, John wrote reports for 47 parks from Acadia National Park (Maine) to Zion National Park (Utah).

He researched and wrote about the widely variable roles geology plays in the landscapes of our national parks from subtle (Herbert Hoover National Historic Site, Iowa) to spectacular (Yosemite National Park, California).

He also participated in dozens of scoping meetings for dozens of parks and accumulated untold frequent-flier and road-trip miles. John and his wife continue to call Fort Collins home, at least when he’s not out in a canoe, preferably in the Boundary Waters. Happy trails (and rivers), John. We wish you the best!

Georgia Hybels, who passed away in 2020, started in 2002 as an intern with a National Park Service air quality information management system program and she joined the GRI team soon thereafter. She was an NPS term employee for eight years and joined CSU as a research associate in 2014, where she continued working for the GRI team.

Georgia was an integral part of the GRI GIS production team and also coordinated the development and production of GRI posters that display our data and accompany the reports. She mentored many CSU student interns who crafted the posters and always made sure new team members were welcomed and included. Her family is working with local parks and the Rocky Mountain Conservancy to place benches as a tribute to Georgia’s love of the outdoors. We will forever miss Georgia’s room-brightening smile, generous spirit, kind soul, and spectacular laugh.

I then met up with the group and everybody relocated to a campground south of Silverton, Colorado. We first focused on the sedimentology of carbonates and siliciclastics, and then on the stratigraphy of the Paleozoic succession in the Animas Valley, with looking in detail at one particularly beautiful roadside outcrop south The CSU Field Camp 2020 students in the San Juan Mountains Photo by John of Molas Pass.
