The south fork of the Bishop Creek Canyon holds vast, thick groves of aspen trees (Populus tremuloides). Since aspen groves are clones, they all leaf out together in spring. In fall they change color simultaneously, resulting in fantastic expanses of canyonsides covered in rich hues of yellow and orange, as if the countryside is aflame. The photo below was taken just off the road to South Lake in the south fork of Bishop Creek Canyon.
