Most geoscientists acknowledge the fundamental importance of field-based research. Many of us have listened to lectures involving numerical modeling of some geological process and concluded that the speaker should see more outcrops. Some scientists appear to have forgotten that geological and geophysical field data have fueled many, if not most, major developments in Earth science. Christopher Scholz celebrates that point in Fieldwork: A Geologist's Memoir of the Kalahari, a highly readable and entertaining account of a microearthquake survey carried out 23 years ago in the Kalahari region of Botswana to investigate the propagating tip of the southwestern arm of the East African rift system and the effects of ground displacements on the hydrogeology of the Okavango Delta.
