The Matterhorn, 40 years after Yosemite Sam and Bugs Bunny introduced me to it on TV.   Impossible to capture its immense presence with an a camera.  

Aare Gorge.  Quietly impressive in scale and length. 

Near Reichenbach Falls, where Sherlock and Moriarty met their supposed ends.  But you knew that, of course. 

Trift Suspension Bridge, traversing the mouth of an enormous glacier.  Not for the weak of heart.  

The Kappellbrucke in Lucerne.  Originally built in 1333.
