At Plateau Point, we enjoyed the sunset with the changing colors in the direction of Zoroaster Temple. The rock became more and more red. Almost no change in the colors happened between 5:30pm and 6:30pm. But then, in the last 20 minutes before sunset, the colors rapidly become much more intensive.
After the sun was below the horizon, we returned to Indian Garden Campground. Zoroaster Temple was still colored red by the last remaining light.
