AN LETH-ALLT The divided burn, or burn with one high bank - from Gaelic This shoreline was once a busy workplace. Local people worked here cleaning and drying diatomite, a chalky white clay found in Loch Cuithir about 4 miles inland. Steam-powered puffer boats moored here and were loaded with sacks of the powdered diatomite ready for sale. Business boomed until the 1950s when Staffin diatomite became too expensive to produce. We do not recommend you walk beyond this point. There is no proper path and the ground is steep and often wet.
