On October 26th, a hole was blasted in the base of 125' tall Condit Dam on the White Salmon River in Washington. In less than 2 hours, the reservoir behind the dam drained completely and the White Salmon flowed unimpeded by a dam for the first time in 100 years.

This short clip is a combination of video and timelapse photography captured throughout the day. The technical stuff:

Video was shot with a Sony FS100, a Sony EX1 recording to a KiPro HDD recorder, and a Canon 5D.
The timelapse photography was done with 2 Canon Rebel T2is and a Canon 7D. Additional cameras used include GoPro Hero 2s, GoPro HD Heros and a Canon 1D Mark 4.

Big thanks to my partner in this project, Steve Stampfli, for all of his ideas and effort.
