Narrow Gauge is a short blue-black bump run that is usually ungroomed, located downhill of Olympia Spur.
It’s accessible from the top of Mary Jane Mountain by veering left off Sidetrack or making a right through the trees in the beginning of Whistlestop.
It spits you out on top of Jane trail.
The trees to right are lots of fun when the snow is fresh.
Narrow-gauge railways were less expensive to operate than standard gauge or broad gauge railways, particularly in mountainous terrain.
