Frozen Canyons of Pluto's North Pole. This ethereal scene captured by our New Horizons spacecraft tells yet another story of Pluto's diversity of geological and compositional features-this time in an enhanced color image of the north polar area, with long canyons running vertically across it. The widest of the canyons is about 45 miles (75 kilometers) wide and runs close to the north pole. The degraded walls of these canyons appear to be much older than the more sharply defined canyon systems elsewhere on Pluto, perhaps because the polar canyons are older and made of weaker material.
