Haha, I have a feeling this Pit Stop location was cooked up on the spot!
So while hunting around Zermatt, I found the location of the tour operator that managed the avalanche/crevice rescue tasks this leg. And their office (if you'd call it one) is located up in the northeastern corner of town, at the side of a steep slope. I got slightly confused following the street signs after those killer stairs, decided to take a straight path instead to the office, and... ended up shin-deep in the snow field that served as the Pit Stop...
And all this time I had no idea it would be the Pit Stop! (I swear I saw paw prints in the snow too!
) Now I wonder if a PA took the same wrong turn while scouting for locations...
(Disclaimer to protect the behinds of the tour operator: no they were very tight-lipped, that's not where I got the information for both sides of the Detour!)
