On February 23, 1925 a Climax locomotive raced out of control down the tracks toward Holder Creek on Tiger Mountain. The locomotive, belonging to the Wood & Iverson logging company derailed near the location of a bridge spanning the small creek. One man, Nick Karis, was killed but others including the engineer were able to jump to safety.* This cache is near the location of the fatal railroad accident. A few rusty couplers, wheels and twisted remnants of a track layer still bear testimony to the accident.
Satellites were tough to hang onto so this may take some searching and that is why I gave it a 3 rating. Just keep in mind you do not need to climb up, slide down, walk through, stomp on or splash in to get the cache, the retrieval is easy.
