Coastal geomorphology thumb|Coastal boulder deposits on the west coast of Inishmore. Person standing next to the large boulder on the bedrock platform gives a sense of scale. This is about 16 m above sea level and 90 m inland. Huge boulders up to above the sea at parts of the west-facing cliffs are an extreme form of storm beach, cast there by waves. Previously considered as possible tsunami deposits, these coastal boulder deposits have recently been shown (by Rónadh Cox and collaborators) to be definitively the work of storms.
