No crazy woman who thinks this river is some sort of transport device will take you along. You are going to stay as far away from her as possible... 

The land is changing as you walk farther into the fields. It gets colder And the grass tips become covered in frost. You were just in a temperate, even warm climate, but now you are no longer dressed for this weather.

There is now snow on the ground. But it is more like heavy frost. It must be thirty degrees out. You are wearing pants and a long sleeve shirt, but you have no coat and you are cold.

You have never seen a change in weather happen so quickly and you wonder why and how it is happening. Your questions are answered when the wind picks up and the world becomes a swirling vortex. The grass is picked up in the air, and dirt is thrown about. There is nothing you can do but hope it will end soon.
