Timber Terror is a wooden roller coaster located at Silverwood Theme Park in Athol, Idaho. Originally, the ride had been called Grizzly, but the park had to change the name to Timber Terror in 1997 to avoid litigation and confusion with the wooden roller coasters of the same name at California's Great America and Kings Dominion. Rocky Mountain Construction founder, Fred Grubb, assisted with the initial construction of the ride. [1]

The ride was designed by park owner and founder, Gary Norton. Similar to the park's larger wooden coaster Tremors, the design was finalized by Custom Coasters International and the ride was constructed in house.

In 2007, Apple released a new version of its Photo Booth application for Macintosh computers as part of Mac OS X "Leopard". This update included looping footage of a portion of the coaster as a novelty video backdrop, which remained part of Photo Booth on every Mac until video backdrops were removed in 2019's release of "Catalina". Even on Catalina, the video of Timber Terror can still be found in its original location in the System folder (within "Compositions," inside the Library folder) on every current Mac computer. Although the backdrop was first released in 2007, the video includes visible "Grizzly" signage indicating it was actually filmed ten years prior in 1996-7.

On September 26, 2010, Timber Terror soft opened to the public with a reversed train as part of the park's annual Scarywood Haunted Nights event. It has run in reverse for Scarywood and the last weekend in September since.

Starting in 2022, Timber Terror has also been partially retracked with RMC's new 208 RetraK. [2]

Wooden roller coaster Type of roller coaster

A wooden roller coaster is a type of roller coaster classified by its wooden track, which consists of running rails made of flat steel strips mounted on laminated wood. The support structure is also typically made of wood, but may also be made of steel lattice or truss, which has no bearing on a wooden coaster's classification. The type of wood often selected in the construction of wooden coasters worldwide is southern yellow pine, which grows abundantly in the southern United States, due to its density and adherence to different forms of pressure treatment.
