I hitched a ride down there with a past geology professor who was take a class on a spring break field trip. This ment we had to stop constantly to look at the rocks and discuss the geologic processes of the region. However, I was more focused on hiking the canyon and less on the geology aspect which did not leave the lasting impression.
"As an adolescent I aspired to lasting fame, I craved factual certainty, and I thirsted for a meaningful vision of human life - so I became a scientist. This is like becoming an archbishop so you can meet girls."
