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.

In 2007, Apple released a new version of its Photo Booth application for Macintosh computers as part of Mac OS X "Leopard".

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.
