This book presents geomorphological and sedimentological aspects of Holocene boulder ridges
along the coastline of western Ireland (the Aran Islands and Galway Bay). Given these boulders'
size extent and altitude they are among the most spectacular deposits moved by marine forces
worldwide and have challenged researchers to solve their enigmatic history. In particular the
question of how their features were formed (by storm waves or by tsunamis) is a matter of
heated debate. The documentation is based on the authors' own field research including
observations on the boulder transport capacity of six extremely strong winter storms in the
2013 14 season. Discussing the arguments published to date and using more than 130 images for
clarity the book addresses the character setting and extraordinary size of these boulders
moved on land comparing them with the situation along other exposed coastlines of the world.
