Aftershock (roller coaster)
Aftershock is a Giant Inverted Boomerang steel roller coaster manufactured by Vekoma located at Silverwood Theme Park in northern Idaho in the United States. This ride is a modified version of Vekoma's popular Boomerang roller coasters.
Layout and Experience
The ride begins when the train slowly backs out of the station and up the vertical lift hill, pulled by the catch car. Once reaching the top of the lift, with riders facing straight down, the train is released and goes through the station and heads into the cobra roll (also sometimes called a butterfly roll or boomerang) inversion. This element contains two of the three inversions found on the ride going forward. After twisting through the cobra roll inversion, riders then go through a single (one) vertical loop and hit the second vertical spike of the ride. Then, a catch car there pulls the train up the second vertical tower, this time with riders facing the sky when they're at the top of the tower. After the train reaches the top of the tower, it is released to coast backward through the layout. The train then goes through the station and heads up the first vertical lift hill again, where it is caught once more and then very slowly lowered back into the station.
