This picture shows the 2010 cliffdiving competition which took place on August 28th in Sisikon, Switzerland.  During the competition, professional divers dive from a 26m high plaform into Lake Luzern and are rated by the judges for their dives. 

Although the 2010 competition took place in rainy conditions, there were still many spectators watching from the shore, the special platform that had been created for the occation (and from which this picture was taken) or boats on the water.  The dives were spectacular.  You can see one of the divers on the platform in this photo. See also this video for a closer look at the diving action.
