Granite is still extracted from Meldon Quarry. The now disused Meldon Aplite Quarry has been designated as a
Site of Special Scientific Interest because of its exposures of
aplite and other rocks. The
Dartmoor Railway terminates at Meldon Quarry; the former continuation of the line to
Tavistock and Plymouth continues as a cycle path. The former railway line crosses the
West Okement River on the
Meldon Viaduct just before reaching the quarry from the west. ==Reservoir==
