At 1.3 km, the landslide transformed into a debris flow transporting mainly forest debris. At 2.2 km, debris<br />

entered an incised stream and carried down a further 1.8 km to Harold Price Creek. Debris jammed over a 150-m<br />

stretch <strong>of</strong> the creek and resulted in re-routing the stream. A debris flood carried logs an additional 3.5 km downstream<br />

to a sharp corner, leaving a debris pile inundation about 100 m onto the floodplain. Of the initial landslide only a minor<br />

amount <strong>of</strong> rock and debris appear to have been transported to Harold Price Creek. The main constituents <strong>of</strong> the<br />

channelised debris flow entering the creek were trees and forest debris. The distance traveled by the rock avalanchedebris<br />

flow was 4 km to Harold Price Creek with an elevation drop <strong>of</strong> 700 m, an overall slope gradient <strong>of</strong> 10 o . Slope<br />

gradient in the depletion zone was about 34 o , dropping to 17 o in the middle zone and 7 o in the zone <strong>of</strong> the channelised<br />

debris flow.<br />

Late on September 18, in Prince Rupert flooding threatened the Mountainview Trailer Park. Floodwaters up<br />

to 3 ft. (90 cm) deep were lapping at the front doors. Slides hit roads and power was cut for varying periods up to six<br />

hours to about a quarter <strong>of</strong> the city. The power was <strong>of</strong>f throughout Port Simpson, in most <strong>of</strong> Digby Island and half <strong>of</strong><br />

Metlakatla. On September 18 at 7 a.m., Port Simpson lost power for more than a day.<br />

Near Oliver Lake, an “impressive” mudslide came down. Another slide came down near Mountainview<br />

Trailer Park. On Mount Hays, a transmission tower went out and slides on Wantage Road just past the city yard took<br />

out two BC Hydro distribution lines. Wantage Road was closed <strong>of</strong>f and a search was activated for a reported overdue<br />

vehicle.<br />

In September, heavy rain caused a beaver dam above the Prince Rupert ferry terminal to break. The road<br />

approaching the terminal was flooded. At the same time the dam broke, a slide knocked out the fibre optics cable and<br />

interrupted power and the computerised system for more than five hours. Luckily, no sailings were scheduled at the<br />

time and service was uninterrupted.<br />

On December 12, a landslide wiped out two poles <strong>of</strong> powerline into the First Nations reserve community <strong>of</strong><br />

Kitkatla. Due to storms and high winds, hydro repair crews were unable to fly in by helicopter. Temporary repairs<br />

were estimated not completed before December 17. *1) On the morning <strong>of</strong> December 16, two helicopters with repair<br />

crews had landed at the slide area and began laying emergency cables. Bad weather, however, forced the eight-person<br />

crew to fly back to Prince Rupert at 11:30 a.m. The storm, which started pounding the north coast on December 12,<br />

produced fierce winds reaching up to 70 km/h on December16.<br />

was the fourth time this year the power had been out in Kitkatla (The Vancouver Sun, December 17, 2002).<br />

On October 26, flooding was reported from Greenville in the Nass Valley. Several days <strong>of</strong> heavy rain caused<br />

washed out roads and cut communication lines in northwestern <strong>British</strong> <strong>Columbia</strong>. On October 25, the Nisga’a<br />

communities <strong>of</strong> Kincolith and Greenville lost power due to a break in the line. Due to fog, BC Hydro crews were<br />

unable to reach the break on October 26. Power was restored to the two communities on October 28.<br />

On October 26, road to Kincolith just completed this year, washed out at No Name Creek, 35 km west <strong>of</strong><br />

New Aiyansh, cutting <strong>of</strong>f Kincolith and Greenville. A bridge was washed out and hard to be replaced. Tentative<br />

reopening date for the road was November 5. The fishing vessel Ocean Virtue brought in supplies. A Prince Rupert-<br />
