Massive earthwork

Tree Mountain - A Living Time Capsule by artist Agnes Denes (1996).
Designed as a long-term reclamation project of a former gravel pit in Ylöjärvi, Finland.

Our Midsummer Eve was warm and partially sunny until the afternoon. The picture was taken a moment before it started raining. Taken from a nearby slope, the blip doesn't show the radial columns of young trees too distinctively; however I chose this shot because the sky looked so interesting.
