Sedimentary rocks...


consisting of Ordovician dolomites greeted us upon arrival at Bear Island (click to enlarge.) The ledgy carbonate rocks provide abundant nesting sites for staggering numbers of shore birds including skuas, puffins, guillemots, gulls, and other varieties.

And yes, I was "blessed" once again by a generous gift of air-dropped guano by countless birds in flight during our late morning Zodiac excursion of the cliff faces.
