Photo showing first mudslide on Highway 25 - 25 May 1962. The eruption, which affected an area 3,000 feet long and one-quarter of a mile wide, struck at 6 p.m. Hundreds of trees up to 100 feet high were snapped in two and tossed about like matchsticks. Eight power poles and 4,000 feet of transmission line were destroyed, cutting off Terrace's power supply. Took out Granite Creek Bridge.

Photo showing first Mudslide on Highway 25 - 25 May 1962. Lake turned Blue. A car and a logging truck were smashed against each other. Two other cars, a pickup truck, three giant earth movers, three caterpillar tractors, a road grader and a drag line were heavily damaged when they slithered into the chasm. A total of 7-1/2 million tons of earth was heaved about in the eruption and hundreds of tons of blue clay were pushed down into the lake itself, turning the water a bright blue.

Photo showing first Mudslide on Highway 25. - 25 May 1962. The whole road was moving and at one place it was tipped to a 45 degree angle. Logging truck driver George Kennedy and Clarence Schroeder, both of Terrace leaped from their huge truck as it sank beneath them. Kennedy said the truck loaded with 7,000 board feet of lumber, swivled and slithered as the ground heaved. He & Schroeder leaped out only to find the earth sinking beneath their feet.

Photo showing Mudslide on Highway 25 - 25 May 1962. About 15-20 people were in the area at the time. Workmen of the Peter Kiewit and Sons Construction Company had gone off shift half an hour before the upheaval and mechanics were repairing some of the heavy machinery. The company is building a new two-lane highway parallel to the old one. One group was working on a caterpillar tractor when the machine suddenly dropped eight feet into the ground, taking a welding machine with it.

Photo showing first Mudslide on Highway 25. 25 May 1962. Kitimat was cut off - travellers have to go by boat to be able to get to the Airport. Government officer, Shaw gave the theory of the earth heave; the layer of blue clay just beneath the earth's surface was unable to withstand the pressure of silt which had absorbed water from a stream running beneath the highway and into the lake. He said his men will drill test holes in the area in the next few days to try to determine how far down the unstable area goes and if there is a solid base for a road. Construction was stopped in the area - a lot of water is still running in and the ground is very unstable. Some workmen found sea shells buried in the clay. Transmission lines and poles would total at least $30,000.
