Granite Rocks And Sweet Ferns

Part of the granite outcrop of Combestone Tor with sweet smelling ferns
Combestone Tor is popular with many a visitor to Dartmoor National Park, being an excellent geological site that offers gorgeous views over the surrounding valleys. It also helps that the tor (old Celtic for a rocky outcrop or pinnacle) is situated less than 70 metres from a nearby car park, meaning that it can be enjoyed by everyone rather than only the most experienced climbers. These outcrops, like the many tors found throughout Dartmoor National Park, are formed through freeze-thaw action over the course of millions of years. Be-fore the Ice Age, when the surrounding land was fertile and covered with trees, water would seep into the bedrock and clean the dirt from above it, exposing it to the elements. When a cooler climate took over and the temperature would rapidly vary over the course of the day, the exposed rock was eroded by the water within it being frozen (and hence expanded) and unfrozen repeatedly.
