I better post this before a serious snowfall. The colorful golden beauty of the first image is that it occurs above the tree line, above 2,000 meters elevation.
The lift, for access to these areas, has already been closed for maintenance prior to the upcoming ski season. So, I screen captured the image from a 24/7/365 webcam, at Jungfrau.ch.
This golden color arises after the evening temperatures regularly drop below freezing. The color will be hidden any day now when the first snowfall arrives. This is a view of the Grosse Scheidegg pass (2,300 meters elevation) just east of Grindelwald.
The last two images are from the Japanese Ginkgo. It holds its bright yellow gold leaves until the first major frost–then the leaves drop almost all at once. At 600 meters elevation, the first frost arrived this week.
