Category 8: Outcrops

Outcrops
Rock outcrops give us important information about geological structures, rock types and past processes. Good outcrops are key to geological mapping and understanding local geological history, and need to be protected from damage, for example as a result of irresponsible coring. This category contains some of the best!
