located on the southwestern edge of ireland’s burren region in county clare, the cliffs of moher run roughly 9 miles along the coast. at their highest they rise more than 700 feet from the atlantic ocean below.
the cliffs were formed between 313-326 million years ago as a result of a river dumping silt, sand, and clay along an ancient delta. this sediment was collected over millions of years & compacted & lithified into sedimentary strata now exposed as the cliff face. the punishing atlantic ocean waves are now eroding the cliffs, causing them to collapse under their own weight.
you may recognize the cliffs of moher from their supporting role as the “cliffs of insanity” in the 1987 epic the princess bride.
I arrived in the early afternoon to an otherworldly view of the atlantic & the infamous cliffs shrouded in sea mist & swept by gusts of cold salt air. the cattle and sheep of the surrounding countryside didn’t seem to notice the bluster, & continued their lunchtime grazing without incident.
the cliffs now see over 1.5 million visitors per year.
