Photographer : JPL Range : 40,000 km (24,8000 mi.) This picture of Triton is a mosaic of the highest resolution images taken by Voyager 2. The mosaic is superimposed on the lower-resolution mapping images taken about 2 hours earlier in order to fill in gaps between high-resolution images. The smallest features that can be seen on the images are about 0.8 km (0.5 mi.) across. The terminator (line separation day and night) is at the top of the picture and is centered at about 30 degrees north latitude and 330 degrees longitude. These highest-resolution images were targeted for the terminator region to show details of the topography by the shadows it casts. Near the center of the picture is a depression filled with smooth plains that are probably ices which were once erupted in a fluid state. The depth of the depression is about 300 meters (900 feet) and the prominent fresh impact crater on its floor is about 20 km (12 mi.) in diameter and about 1 km (0.6 mi.) deep. On the right is a elongate crater with adjacent dark deposits about it. This feature may be an explosive eruption vent formed by gaps within the ice. The linear structure on the lest is probably a fracture along which fresh ice has been extruded.
