What happens when immovable objects meet immutable forces? Wild landscapes form, such as this one at the head of Loch nan Uamh where the surging waters of the Atlantic Ocean have spent eons waging battle with the buttressed rocky mounds of the Scottish shoreline. This day, however, finds a tenuous peace in place: the sea is all but becalmed and the gnarled rocks are free to release their burdens under the warmth of an autumn sun. Through this scene tiptoe graceful concrete arches supporting the West Highland Line's Loch nan Uamh Viaduct, built in the late 1890s and unusual for its siting in the midst of a sag vertical curve. For reasons unknown the mid-day First ScotRail departure from Glasgow has all but stopped at mid-span -- perhaps to give the passengers a lingering view of this scenic wonder in the waning minutes of the day, and unwittingly allowing this photographer just a wee bit more time to attempt to get his shot just right. Mission accomplished.
