Karst landscape geology
“Cutaway artwork showing the features of a karst limestone landscape formed by erosion. The limestone rock has been shaped by natural chemical erosion. Carbon dioxide in the air dissolves in rainwater to form carbonic acid. This acid erodes the limestone rock as the water flows over it. At far right, a river flows down into the ground to form an underground river (across bottom), emerging at lower left. Two layers of caves are shown, with water seeping down from above to form stalactites, stalagmites, which can join to form large pillars. At left, the rock has been exposed, forming a limestone pavement.”

Toad River Valley, Canada

Like curtains drawn across the landscape, the walls of the Toad River Valley yield to untracked forests and pure lakes in northeastern British Columbia. Years of compromise and careful planning defined the enormous Muskwa-Kechika Management Area here, where competing interests—from miners, outfitters, preservationists, and native peoples—coexist in delicate balance.

A small dock in the village of Gjógv, in the Faroe Islands - Jürgen aus Rheine @ fotocommunity
I had to look up the Faroe Islands to find out exactly where it was located.  It is interesting.  More at Wikipedia if you are interested: http://en.wikipedia.org/wiki/Faroe_Islands
The settlers are not thought to have come directly from Scandinavia, but rather they were Norse settlers from Shetland and Orkney, and Norse-Gaels from the areas surrounding the Irish Sea and Western Isles of Scotland. The old Gaelic name for the Faroe Islands Na Scigirí means the Skeggjar and probably refers to the Eyja-Skeggjar (Island-Beards), a nickname given to the island dwellers.
