A fresh impact crater can be seen in the large, smooth area to the right of this image of Triton. The low cliffs to the left may have been caused by melting surface materials or fluids that flowed sometime in Triton's past.
The small white spots in this close-up of Triton appear to be frost around volcanic vents. The colors may be due to methane (pink) and nitrogen (white).
