When the copper poles slide off the driver's roof towards the car Sarah and her family are in, the ends start off perfectly round, then suddenly become sharp and pointed, then become round again when shown in the aftermath of the accident.

Errors in geography 

On the 4x4 can be seen UK-spec headlights for left-hand traffic, showing that the vehicle in question was definitely not in North Carolina.

Factual errors 

While the rock climbing scenes in this movie are technically an order of magnitude better than most Hollywood attempts, when Juno follows across the first chasm, she wouldn't have bothered to re-rack the cams she was collecting to the gear loops on her harness. Completely unclipping them from the rope is both unnecessarily energy expending and dangerous, since she could easily drop a free cam into the abyss below. Most climbers faced with following a leader on a roof like that would simply disengage the cam from the rock and let it slide safely down the rope where it would collect by the climber's harness for later racking.

The cave drawings featured a woolly rhinoceros which lived in Eurasia. None have been found in North America. They lived during the Pleistocene epoch (1,808,000 to 11,550 years before present) and are known mainly through cave drawings. Recent carbon dating has shown that populations may have survived as recently as 8000 B.C. in Western Siberia. A nearly complete specimen was also found in a tar pit in Starunia, Poland. The oldest known cave paintings are approximately 40,000 years old.

When Holly dies, her pupils contract. At death, however, pupils dilate, not contract.

All of the spines in the various bone piles throughout the movie have the spines intact and the inter vertebral disks still present in the spines. Inter vertebral disks, however, are cartilage, not bone, and would have decayed (especially given that there is no clothing, hair, or fur in the bone piles, meaning that the bones are quite old). The spine segments should be scattered and in pieces, not in long segments.

Cars in North Carolina are not required to have front license plates. Also, the license tag is made up of four digits followed by three letters; on North Carolina plates, letters precede numbers.

Revealing mistakes 

The green light almost never matches the green glowsticks supposedly casting them. Several times the actors' shadows fall in the direction of the glowstick, rather than away from it.

Several times throughout the movie, as characters brush up against stalactites you can see the stalactites move. Stalactites are rigid formations and do not sway or bend with contact.

Spoilers 

The goof items below may give away important plot points.

Continuity 

Towards the end when Sarah is driving along the road, the road markings change from US to UK. This should only be considered a goof in the US theatrical release. In the Director's Cut, Sarah is hallucinating the entire escape sequence, and any goofs can be considered part of the hallucination.

Continuity 

When Juno falls into the pool towards the end (just before finding Sarah), when she resurfaces from underwater, her ice pick is bent. However, she then uses a straightened ice pick to help her climb the wall.

Continuity 

When the girls reach the cave, the blue truck parks and the BMW parks on its left side. When the last girl reaches the surface, she gets in the blue truck. When she goes to the truck, the beamer isn't there, but when she pulls out it's on the left again. This should only be considered a goof in the US theatrical release. In the Director's Cut, Sarah is hallucinating the entire escape sequence, and any goofs can be considered part of the hallucination.

Continuity 

In the end, when Sarah has parked her car at the side of the road, the entire car is on the grass. When the trailer almost hit her, the car is back on the road. This should only be considered a goof in the US theatrical release. In the Director's Cut, Sarah is hallucinating the entire escape sequence, and any goofs can be considered part of the hallucination.

Crew or equipment visible 

When Holly drops and breaks her leg, about 45 minutes into the movie, the slip-wire is visible, reflecting in the light from the flashlights.

Errors in geography 

In the end, a logging truck is depicted speeding by on the North Carolina highway. The tail markings, reflectors, and technical gearing on it represent UK transit requirements instead of standard USA (OTR) specs. This should only be considered a goof in the US theatrical release. In the Director's Cut, Sarah is hallucinating the entire escape sequence, and any goofs can be considered part of the hallucination.
