Where the snow still sits was once the home of glaciers 8,000 years ago.
The landscape that we see today, hills, valleys and rivers, were shaped by the melting of the glaciers. As large chunks of ice broke off and slid downwards, sweeping away the alluvials before, them they carved new shapes in the land. All of that is so easy to see and appreciate just before the last snow of winter melts away.
We travel this narrow road several times a week and only when a photo is taken do we actually see the beauty of its' form with all its' twists and turns.
