A modified refractor telescope stands on a cut stump in the forest, next to a plywood sign reading HAV (ocean) and, upside down beneath it, FJELL (mountain). Looking through the telescope is looking into the past: a refractor flips the image, so the mountains appear above the ocean — correct, upright. Looking at the sign directly, without the telescope's correction, hints at a future where the ocean has risen to cover the mountains.
