I found this stunning photo of a Russian tree while reading a Swedish magazine called Research & Progress (Forskning & Framsteg in Swedish) and was blown away. Isn't it amazing? Each column is one year in the tree's life, and the thin column with the aberrations is from the year 536, when a severe frost hit in the summer.
Of course I always think of trees as being so solid, and it's fascinating to see their underlying structure. Have you seen any close-ups that have shocked you? Please share!
