With a loud rumble, the final blast to demolish the Glines Canyon Dam occurred August 26, 2014, at 4:12 p.m.
The blast met contractor objectives by pulverizing the remaining 30 feet of dam and its underwater support structure known as the dam apron.
The blast was preceded by several weeks of preparation. Contractors first built a temporary access ramp so that an excavator and drill rig could be used to create an extensive pattern of holes into the remaining dam and apron. Blasting experts were on scene all day today to pack the holes with dynamite and set the charges.
“This final blast is a milestone – the Glines Canyon Dam no longer exists,” said Olympic Natinal Park Superintendent Sarah Creachbaum.
The contractor estimates another six to eight weeks of work to remove the rubble and debris from the channel.
“Like so many others, from our visitors and neighbors to the hundreds of interested scientists and students, we are excited to watch the restoration process continue to unfold in the coming years,” said Creachbaum.
