Graphic Logs

    Observations and measurements of rock data need to be methodically recorded in the field.  This is usually accomplished by  constructing a graphic log in your field notebook, supplemented with field sketches, and photographs. Graphic logs are a standard way of compiling descriptive information in a concise and visual manner and they graphically document features such as mean grain size, bed geometry, sedimentary structures, paleocurrents, fossils, and colors, etc. from the base of the outcrop to its top.
