Frank Ethridge Symposium

September 15-16, 2018

Warner College of Natural Resources


Thanks to everyone who attended the Frank Ethridge Symposium! Professor, geologist, adviser, colleague, and friend, Frank joined the Colorado State University faculty in 1975 and continues to enrich the geosciences department as an active professor emeritus.

Events included a daylong Saturday symposium featuring talks by Frank’s former students, lifelong colleagues, and CSU faculty. It was followed by an evening reception and dinner where multiple generations of Geosciences friends and colleagues participated in a tribute to Frank’s exceptional legacy.

On Sunday, Frank and faculty member John Singleton led a field trip to nearby Lory State Park.

If you wish to honor Frank’s exceptional legacy by supporting future generations of sedimentology and petroleum geology students at CSU, kindly consider a generous contribution to the Ethridge Endowment.
