In the over the shoulder shots of Ben and Jonathan at the top of the rock column, the shadows of the surrounding mesas are short yet the frontal shot of the two show the surrounding shadows to be long as if it is late in the day.
In the hotel at the foot of the Eiger, Jonathan looks out the window to see Pope surrounded by people at the outside tables yet in the long shot of the climbing team, the outside area is empty, yet when Jonathan goes outside to meet Pope, the area is again filled with people.
After Dewayne is killed, his swollen and bloody lip from the beating given to him by Hemlock the day before is missing, even though it was still present at the resort just minutes before the chase in the desert where he is shot.
The place in the desert where Hemlock leaves Miles is near the base of the needle rock that Hemlock and Bowman had just climbed, and it can be seen behind them when Hemlock stops his Bronco to let Miles out.
When Hemlock is shown on top of the hill near the mountain resort where they will climb the Eiger, the down wash from the helicopter filming the shot as it approaches him can be seen blowing the grass around him as well as his clothes and hair.
At about 64 minutes into the film, Hemlock and Bowmen climb that high, thin, pillar-like formation, when Hemlock helps Bowmen onto its top, you can see the shadow of the camera, first on Bowmen as he crosses in front of it, and then on Hemlock's white t-shirt where for a moment you can also see the shadow of a cable as well.
When the four mountaineers first encounter the ice and snow on the Eiger after the rapid weather change, they are forced to use their ice axes to be able to climb. During this scene there are various axe holes already in the ice whilst they are climbing upwards indicating that there had been a previous take of this scene.
After Montaigne is hit on the head by falling rocks during the Eiger climb, the next morning it is revealed he died during the night, however his 'body' can be seen clearly still breathing (as he lay frozen just behind Clint Eastwood).
