Inishmaan (Irish: Inis Meáin, the official name, formerly spelled Inis Meadhóin, meaning "middle island") is the middle of the three main Aran Islands in Galway Bay on the west coast of Ireland. It is part of County Galway in the province of Connacht. Inishmaan has a population of about 160, making it the smallest of the Aran Islands in terms of population. It is one of the most important strongholds of traditional Irish culture. The island is predominantly Irish-speaking, though many inhabitants have knowledge of English, and is part of the Gaeltacht.
The island is an extension of The Burren. The terrain of the island is composed of limestone pavements with crisscrossing cracks known as "grikes", leaving isolated rocks called "clints". The limestones date from the Visean period (Lower Carboniferous), formed as sediments in a tropical sea approximately 350 million years ago, and compressed into horizontal strata with fossil corals, crinoids, sea urchins and ammonites.
Glaciation following the Namurian phase facilitated greater denudation. The result is that Inishmaan is one of the finest examples of a Glacio-Karst landscape in the world. The effects of the last glacial period (the Midlandian) are most in evidence, with the island overrun by ice during this glaciation. The impact of earlier Karstification (solutional erosion) has been eliminated by the last glacial period. So any Karstification now seen dates from approximately 10,000 years ago and the island Karst is thus recent.
