S.F. Emmons Lecture
The S.F. Emmons Lecture, which began in 1962, is a highlight of the Colorado Scientific Society’s activities and contributes not only to our standing in the scientific community but to the intellectual growth of our members and colleagues. The series is named in honor of the Society’s founder, S.F. Emmons. Generally presented at the January meeting, the lectures feature speakers that are recognized nationally or internationally as being at the forefront of research in some important facet of the earth sciences.
