On all field excursions you will be asked to draw field sketches to illustrate the relationships between rock formations. Keep the following points in mind:
Decide whether the sketch is to be a map, a view or a cross-section.
Draw a sufficiently good sketch to photocopy and paste into a report.
Make the sketch resonably large, say 8 to 12cm wide.
Pick out the main features with bold lines (use a HB or 2B pencil).
Give the sketch a definite title. For example View of...
Give an orientation. For example View of ... looking North.
