In April 2007 I had the rare opportunity to shoot some panoramas on top of the dome of the Sphinx observatory on the Jungfraujoch. It was a very cold day with minus 15-20 degrees Celsius, plus winds of 40-50 km/h. The dome itself provided just enough space to sit on its rails, with a vertical drop of 1500 meters on one side.
One week later I climbed the Mönch and one day later the summit of Jungfrau with absolutely stunning weather conditions. The summit ridge of the Mönch is very narrow and just wide enough to hold your feet.
All these images were shot on behalf of the Swiss National Museums for the exhibition project «Alpine Panoramas - Highlights of Swiss photography».
