Silver Birches---- the essence of the land

Of all the trees, silver birches always touch the string of my heart, partly due to my early childhood memory of my daily encounter with them . I joined Fengping's high school reunion team for a short trip today , so I got a chance to head for the deep valley of Altay Mountains where Kolang River originates and , where silver birches dance and stretches their limbs into the blue sky.  Did this quick oil sketch while having a short break on the way to the mountains.
