Estimate height

Measure section

Establish competence in basic trigonometry in order to: 1) know the appropriate measurements to obtain in the field, 2) be able to obtain these measurements reliably and accurately, and 3) be able to utilize these measurements to construct maps, crosssections, and block diagrams.

Be able to record (

“log”) field notes of samples, observations, and measurements adequately, such that you or a professional colleague can utilize this log to make a map or describe a stratigraphic section at a later point in time, back in the office or lab.

Be able to measure and describe a stratigraphic section.
