She started at 83 South, inland and is on snow, we can be pretty confident it isn't salty.

The snow here is unlike anything I have seen. There is no precipitation and it is so cold there's no moisture in the snow. It's like sand: gorgeous to look at, grainy to the touch and a nightmare to cycle in as it parts like waves under our tyres.

Fair play to her!
