Abstract: Nearly 100 year old tunnels once used by the Kettle Valley Railway are now popular destinations for hikers and bikers in the Myra-Bellevue Provincial Park in British Columbia. These tunnels have never undergone detailed geotechnical mapping and remain largely unsupported and subject to freeze-thaw cycles and gradual deterioration resulting in some loose rock and small rock falls. Stereo photographs are being taken to establish high resolution digital rock surface models of the tunnel interiors and tunnel portal areas. These models permit accurate mapping of important geological structures and form an archive that can be used to identify changes in the tunnel conditions over time. The capability to monitor changes in the tunnel surface could become critical in detecting and managing possible rock fall hazards.
