The Beast and Jean find themselves stranded in Antarctica. Luckily Jean's frantic attempts to get back underground to rescue the others attracts the attention of a helicopter pilot (I know, I know, it happens anyway) who rescues them. Returning to the mansion, Professor Xavier comes to believe that the other X-Men are dead. But, of course, they're not dead; instead they've wound up in the Savage Land and they too think that the others are dead. After having to deal with the local wildlife, the X-Men stay at a village, where Cyclops realizes he feels nothing after Jean's "death" while Colossus knocks up a local girl (no, really). After going off for a bath, Ororo disappears, and the X-Men soon learn that she's been taken by their old enemy Sauron.
Continuity Notes
Much, much later in Uncanny X-Men Annual #12 we find out that Colossus does sleep with one of the women he walks away with and she does get pregnant with a child, who is named Peter. He never gets referenced again, but I'm always impressed when superheroes leave behind illegitimate children.
Comments
Usually I love stories that show the universes of the Big Two to be wild and diverse places, but I''ve never really liked the Savage Land in any of the stories I've read. It's not that I'm against the whole Tarzan riff, but it always seems like the Savage Land is one of those elements that keeps being brought back for its own sake, not because the writers actually have any new stories to tell about it. Worse, this story brings back probably my least favorite villain from the X-Men's Silver Age period, Sauron, who just seems like one of those characters you can't even explain to people who don't read superhero comics ("Well, see, first this guy and his girlfriend were attacked by pterodactyls from Antarctica in Tierra del Fuego...") And this story hasn't really changed my mind.
