bleffort mi ha fornito il link originale da cui ha tratto l'immagine:

Anche in questo caso io non vedo altro che conformazioni naturali e luce molto radente... a voi la parola

NB:
le immagini originali risultano più allungate perchè hanno un fattore di scala diverso tra orizzontale e verticale (Vertical Pixel Scale 0.005850
Horizontal Pixel Scale 0.003462)
