Geography and Geology
Like most of the other islands of Orkney, the bedrock is Middle Old red sandstone of Rousay type of the Devonian period, but much eroded and tilted.
The islet is separated from Copinsay by Horse Sound, and to the south west is Corn Holm. Mainland Orkney is due west, and Auskerry and Stronsay are much further to the north. The Horse is the easternmost of the southern Orkney islands.
The Blaster Hole is a sea jet, of the type known in the Northern Isles as a gloup. When a storm blows in from the east, the aptly named Blaster Hole can produce a spout of nearly 60 metres (200 ft) highly, solely by wave power.

Famous quotes containing the words geography and and/or geography:
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
“Ktaadn, near which we were to pass the next day, is said to mean “Highest Land.” So much geography is there in their names.”
—Henry David Thoreau (1817–1862)
