#WaterfallWednesday Pic from today's walk to the wonderful Eas Dubh, east of Shiaba, in south Mull. Waterfall is maybe 25m high. Upper part of cliff is columnar basalt flow, lower part is a mixed sediment/volcaniclastic unit (both Palaeogene). Aslo a wee rainbow at the bottom 🌈 😊 #Mull#Geology#Waterfall#Rainbow
