The Long Ascent

This is a 3D render that I modified in Photoshop. The figures were painted on a much larger scale, then reduced and placed in the landscape.

I haven't the slightest idea what this is, but it does not look like a natural formation. I think it's a structure - its origin and purpose unknown.

The image was originally created for a book project, and I added the figures much later. A lot of material didn't make it into the book - but it might find its way here...
