Industries lumber mill, which employed about 250 people, might be forced to close. Barge service down the Nelson River and the mining industry also suffered due to the rail break. On August 3, rail service between Fort St. John-Fort Nelson was scheduled to resume after Fontas River washed out the line in July. However, the opening date was further delayed to the first week of October. Rain and mushy muskeg terrain hampered the repair work. September 25-26, 1973 Event type: Flooding. Precipitation: Falls River (51.8 mm/1 day), September 25, 1973; Sewell Inlet (58.2 mm/1 day), September 25, 1973; Tasu Sound (49.8 mm/1 day), September 25, 1973; Kemano (91.7 mm/2 days), September 25-26, 1973; Kildala (81.5 mm/2 days), September 25-26, 1973; Bella Coola (103.1 mm/2 days) September 25-26, 1973. Source: Environment Canada 1991; Church 1983 (pp. 169-180); Church 1988 (p. 226). On September 27, the Bella Coola River above Brunt Creek recorded a maximum instantaneous discharge of 682 m 3 /s and a maximum daily discharge of 541 m 3 /s (Environment Canada 1991). During this flood in the Bella Coola River, major destabilization occurred in the Big Bend reach. Upstream from Tastsquan Creek fan, the “big bend” near Bella Coola village was cut off when sediment filled the former channel, which had persisted for nearly a century (Church 1983; Church 1988). January 14-21, 1974 Event type: Fatal snow avalanche. Precipitation: Kildala (281.2 mm/8 days), January 14-21, 1974; Kitimat Townsite (320.1 mm/8 days), January 14-21, 1974; Kemano (175.2 mm/3 days), January 16-18, 1974; Falls River (191.7 mm/6 days), January 16-21, 1974; Sewell Inlet (79.2 mm/1 day), January 17, 1974; Terrace (99.1 mm/1 day), January 17, 1974; Kitimat Townsite (96.5 mm/1 day), January 17, 1974; Prince Rupert M.

Ministry of Transportation and Highways 1980; Godfrey et al. 1974; Stethem and Schaerer 1979 (pp. 89-93). On January 17, 118.1 cm of snow fell in 24 hours at Lakelse Lake near Terrace, setting the Canadian record for the greatest snowfall in one day (Phillips 1990). *1) Terrace reported 99.1 cm of snow on January 17 and 40 cm of snow on January 22. The Terrace airport recorded 237 cm of snow in 11 days. Before January 14, 172 in. (4.37 m) of snow fell. The heavy snowfall was followed by a sharp rise in temperature. During the week before to the storm, the temperatures were very low, rising to 0 o C during the storm. On January 22, a “dry” avalanche came down 28 mi. (45 km) west of Terrace. It wiped out a service station and motel-restaurant complex North Route along Highway 16. The service station had been built in 1964. It was located in the run-out zone of large avalanches that would probably occur once in about 15 years (Stethem and Schaerer 1979). According to a National Research Council report, tree growth patterns and broken wood in the area demonstrated that avalanches had reached the highway through two narrow gaps before the café was built. The North Route buildings stood directly in the path that dry, rapidly moving avalanches would be expected to take. “Unfortunately, the hazard was not recognised when the service center was built,” the report states. “And later, when avalanches did come close, the warning went unheeded.” (Terrace Standard, January 21, 2004). Several vehicles were also buried. Seven people were killed. *2) The snow mass was estimated at 400 ft. (120 m) long, 100 ft. (30 m) wide, and 30 ft. (9 m) deep. The avalanche traveled 500-600 ft. (150-180 m) down and 1,000-1,500 ft. (300-450 m) across. D.D. Godfrey, Highways Department regional engineer for Burnaby, estimated the speed at which it traveled to be over 100 mph (160 km/h). The estimated speed of the avalanche when it hit the buildings was 108 km/h (Stethem and Schaerer 1979). The avalanche snow ranged from 1-8 m in depth and was strewn with housing debris and trees up to 0.5 m in diameter. The average depth was 1 m, but the snow in the area surrounding the buildings was up to 8 m deep. The avalanche ran out on the ice of the Skeena River, with the tip of the deposit 250 m past the service centre. On several trees between the railroad and the river, snow was plastered on the north side of the tree trunks up to 30 ft. (9 m) above the tracks. Snowfalls at the accident site are usually greater than those at the Terrace airport. At the North Route site, the snowfall was probably greater by one third (Stethem and Schaerer 1979). Earlier that morning, a Canada Post mail truck driver and only survivor, heard “a bunch of noise rattling outside.” He was told not to worry as “it’s way up in the hills.” Just after 8 a.m., the slide hit. “I heard it – just like a cannon shot,” he said. It pushed him through the wall of the coffee shop and 50 ft. (15 m) beyond. During the rescue operations, a smaller slide occurred about a mile (1.6 km) from the disaster site. At 2:45 p.m., almost seven hours later the first body was found under 3.6 m of snow. Zobel was the second victim found, and he would be the only survivor. It was nearly 20 hours after the slide hit that the last bodies were found. The only other survivor was a husky. The dog was under a building and crawled out a couple of days later. 116

The coroner’s inquiry found that logging carried out by the service station owner was a contributing factor to the slide. He had logged off an area above his property on Highway 16. Warmer temperatures loosened the heavy snowpack on the mountain above the highway triggering a fast moving powder snowslide. (The Vancouver Sun, March 21, 1974). Highway 16 between Prince Rupert-Terrace was closed for 12 days. Major slides occurred at 25 locations. At Mile 35, a slide knocked down the telegraph) line and at least six other slides came down. Between January 14-18, Kitimat recorded 246.2 cm of snow. This made it the second greatest snowfall in five consecutive days, just short of the Canadian record held by Pointe-des-Monts, Que., which recorded 248.9 cm of snow between March 16-20, 1885 (Phillips 1990). According to John Cruikshank of the Fire Department, Kitimat recorded a total of 149.2 in. (3.78 m) of snow between January 11-22. The Terrace airport had 93.4 in. (2.37 m) of snow. On January 22, the roof of the Ocean Falls High School collapsed. There were no injuries because the accident happened 1.5 hours before school started. The building had only been open since September 1972. The collapse was caused by heavy rain on top of 16 in. (40.6 cm) of snow on the flat-roofed structure. An avalanche at Boathouse Hill blocked the highway linking the Bella Coola townsite with the local docks (Godfrey et al. 1974). ---------------------------- *1) On February 11, 1999, this record was broken when Tahtsa Lake recorded the greatest single-day snowfall of 145 cm. (Times Colonist, January 26, 2003). On the same day, Terrace set a new one-day snowfall record with 113.1 cm. (Terrace Standard, February 17, 1999). The total snowfall for the Terrace airport for January 1974 was a new record for the month. *2) Following the fatal avalanche, the provincial government engaged freelance avalanche consultant Roger Tremblay of Stewart to set up a new system of snow control along the highway between Prince Rupert-Terrace. The Highway 16 program would be followed by the establishment of a group to study snow conditions over the province as a whole. (The Vancouver Sun, January 31, 1974). February 17, 1974 Event type: Fatal snow avalanche. Precipitation: Not applicable. Source: The Province, February 18, 1974. On February 17, an avalanche on Mica Mountain close to the Alberta border, 7 mi. (11.2 km) west of Valemount killed one man and seriously injured two others. The avalanche was caused by the upper layer of snow fracturing at the top of the mountain. Mild weather and wind conditions had led to the layering in the snow. The 0.5mi. wide slide thundered 3,000 ft. (900 m) down the mountain. Geoffrey B. Taylor, 44, of Montreal was buried under 3 ft. (90 cm) snow and suffocated. With the aid of avalanche radios, the victim was found in a maximum of 20 minutes. Four other skiers were treated for minor injuries. The injured skiers were on the edge of the avalanche and were hurt when thrown against trees by the slide. All the skiers injured belonged to a party of 40 skiing in groups of 10 under an experienced guide. The groups were skiing at different levels on the 3,000-ft. ski run. The heli-skiers were a party mainly from Germany and eastern Canada and the U.S., organised by Canadian Mountain Holidays. They were skiing with the help of two helicopters, which carried the injured to the hospital. One helicopter almost got swept away. It had just taken off from the bottom of the ski run when the avalanche came down. March 6-8, 1974 Event type: Snow avalanche. Precipitation: Not applicable. Source: The Province, March 9 and 13, 1974. On March 8, a snowslide blocked about 200 ft. (60 m) of Highway 16 at Telegraph Point, approximately 50 mi. (80 km) west of Terrace. During the previous days, snow had been falling heavy in the area. The highway was expected to reopen early on March 9. This was the first snowslide to come down onto Highway 16 since the provincial government had set up a new system of snow control along the highway between Prince Rupert-Terrace in January. *1) -------------------------- *1) Daily patrols and weather reports were being used to check possible snowslide sites along the highway. It was one of the recommendations in the first report from Roger Tremblay to Highways Minister Graham Lea. (The Province, March 13, 1974). June13-25, 1974 Event type: Spring runoff flooding.
