Continuity mistake: When the rescue team are jumping from the helicopter to the side of the mountain, the chopper suddenly swings causing Monique to dive for cover. When she dives to the floor there is nothing around her only snow and ice, yet in the following shot when the propeller blades are close to her, a large rock has appeared to her right which wasn't there in the previous shot.

Factual error: When the expedition is unloading from the helicopter, it shows a view of the lady with the helicopter blades about to cut her head off. It then shows a view of the helicopter, perfectly upright, and people are still jumping off! She then gets up and crawls to the rock wall, which in a full view you can see that it is at least 15 feet away from the edge. The helicopter blades follow her, perfectly parallel with the ground. It is physically impossible - the helicopter would have to be underground for this to happen.
Factual error: When Chris O'Donnell is inside his tent talking on the radio with his trapped sister, they're talking like they're on the telephone, like if they can interrupt each other at will. On a radio, you can only hear the other guy after you've stopped talking. That conversation could never have taken place like that. Besides, they never press the "send" button.
Visible crew/equipment: Just after Vaughn and the others have started there climb up K2, Annie is pulling herself across a rope from one mountain to another. In the reflection of Vaughn's goggles, in his close up, the large white panel and what looks like a camera are visible. (00:29:15)The-Immortal
Continuity mistake: When we see Peter in the hut taking photographs, in the previous shot from a small distance from beyond the two tigers, there is only one large rock then one behind that one. When the shot goes to Peter's camera there is now two small rocks in line with each other. (00:06:35)The-Immortal
