SUMMERLAND – Heavy equipment was working throughout the day Monday clearing away a rock slide that swept down Sunday onto Highway 97 north of Summerland.
One car struck a concrete barrier that was dislodged by the slide.
The two occupants from Alberta suffered minor injuries.
About 1000 cubic metres of material, enough to fill 100 dump trucks, let loose.
While the debris is being removed the four lane highway has been restricted to a single lane in each direction at the slide site.
The highway is expected to fully reopen Tuesday.
The slide occurred at a section of the steep hillside that is not secured by long bolts driven into the rock, as are adjacent areas.
There has been speculation it may have been triggered by a a small earthquake.
But a seismologist with the Pacific Geoscience Centre near Victoria says their equipment did not detect any tremor activity Sunday in the Okanagan.
