It is known by many names: quaking aspen, golden aspen, mountain aspen, poplar and trembling poplar.
The 7000 years old green and red bog can be reached through trembling poplars, alders, swamp- and birch galleries.
Trees were scarce in that part of the valley and only about a mile upstream on the Water of Girvan, trees petered out at a place where trembling poplars grew.
Also known as trembling poplar, flattened petioles on the leaves cause them to flutter in the wind.
Through the blackness, the sky glues to the trembling poplars.
