Other mistake: About seven minutes before the end, the geologist and company and a Highway Patrol car go to the edge of town to get a better view. As the Highway Patrol car skids to a stop look on the road and there is already a longer skid mark. I'm guessing that in the first take the car skidded too far.

Continuity mistake: When the geologist parks in front of his office, the back of the station wagon is a good six feet left of the door. When the newspaper man walks across the street to visit, the back of the car is now even with the door. In a later scene when the other geologist arrives, the back of the car is once again about six feet from the door.
