"On first examining a new district, nothing can appear more hopeless than the chaos of rocks; but by recording the stratification and nature of the rocks and fossils at many points, always reasoning and predicting what will be found elsewhere, light soon begins to dawn on the district, and the structure of  the whole becomes more or less intelligible." - C. Darwin

“The person in charge of the field observations should always keep in mind that field observations could as well be performed by a recording machine unless the findings produce reactions in the brain of the observer and are utilized as tools for improvement and clarification of ideas”. - K. Terzaghi
