Boulder Mountain


2002 (Boulder Mountain Set)



 Boulder Mountain was a destination included with the Boulder Mountain Set and the Boulder Adventure Expansion Pack. When the button at the bottom of the mountain is pressed, Boulder rolls down the grooves and falls onto the track, which collapses a resettable signal house.

  • In the Boulder Adventure Expansion Pack, the model of Boulder Mountain was significantly downsized and was referred to as Track Hazard Mountain.
