| Popis: | Dartmoor Vlei is a 42 ha unchannelled valley-bottom wetland located in the headwaters of the Mnyamvubu River in the KwaZulu-Natal Midlands, South Africa. The wetland and its catchment are underlain by a large dolerite sill that forms the Karkloof escarpment and plateau and the wetland terminates against a dolerite dyke that has intruded into the sill. The dolerite sill has been deeply weathered to depths in excess of 7 m, while the dolerite dyke at the toe of the wetland has not weathered such that water flows across bedrock at a depth of |
