Our first snow hike this winter. The trail from the village of Planinitza to peak Tumba and back is one of our favourite December destinations. Cherna gora is a low mountain, the trail is easy and in the open and runs by fields and up and down small hills, with pleasant views to other mountains around. Because it is in the open and fairly level, it is extremely pleasant on a warm and sunny December day. And today was supposed to be one of these days.
We watched a very interesting phenomenon during the entire hike - the sky to the east was yellow-reddish, like during sunset or sunrise, only it was around noon and the sun was actually above us. I suppose it is some kind of refraction of the sunlight into the thick clouds above us, but I'm not sure. Anyway, it was beautiful and unusual.
