FATMAP difficulty grade
From the top of Gemsstock you ski south - about 35 degrees for a few turns, then a flat part and again a 35 degree part a bit longer and more traversing.
When you arrive under a little pass on your right (west) which is about 100 metres higher, start to walk.
There are often tracks for skins and for foot-steps.
At the pass called Guspis your run starts.
You cannot miss the way, just follow gravity.
When the valley turns right (north) it is better to keep on the left side of the river/gully because it is easier.
Keep skiing until the pass road of St.
There, by the ventilation funnel, you have to walk a 100 metres up to the road that brings you easily to Hospenthal where there is a twice hourly ski bus back to Andrmatt. There is very often wind here and the slope can become crunchy and blown if there has not been a recent snow fall.
Don't do this run if you're tired!
