Your interpretation of this image is invaluable.

It is wonderful how knowledge of the Earth (geo logos) can be so useful and insightful applied to an alien
landscape at the far edge of the solar system. Likewise, how studying that alien landscape can yield such
useful, practical insights into our own home planet.

As for "interpreting the relief correctly", isn't it odd that we all perceptually interpret an areal image
best if we place the source of illumination up and to the left? All shaded relief maps are drawn this way,
even though except for afternoons in the Southern Hemisphere, the Sun is never in the North West.
