@thomasfuchs i can't tell if this is based off an actual stretch of road out by Point Reyes, and if so how closely (the distant terrain definitely looks like it could just be a perlin heightmap or somesuch) but i know this stretch of land pretty well... it might be the view south down Oyster Road heading towards Drake's Bay (38.083867 x -122.931750 roughly). either way, lovely image for 1983 and a bit of lucasfilm history i wasn't aware of.
@jplebreton @thomasfuchs I think this image predates the publication of Perlin noise (1985). The mountains were, I believe, done by Loren Carpenter. Here's a nice interview where he explains the technique and inspiration: https://www.youtube.com/watch?v=y5moYMIp8iU
