Doubtful the ranger had the scale cliffs ability. There's no number beside the unit flag.
Besides, many turns prior I discovered the island, and to my surprise my unit (no cliffs ability) was able to clamber on it ("move to" command showed a route from the eastern-most sea tile). But after getting on, couldn't get off. Reloaded. Just a bug probably.
