Abstract
The Katz slide located near Hope, B.C., is the site of two large prehistoric rock avalanches. Much of the debris field of the older of the two landslides is buried beneath floodplain sediments, thus its distribution over the valley bottom is still unclear. Ground penetrating radar (GPR) was used over this older deposit to test the ability of the equipment to resolve buried, very course substratum and to map the extent of the deposit. Two GPR facies were the most distinct out of seven. One facies consists of chaotic discontinous, hyperbolic reflectors that are interpreted as blocky landslide debris. The other facies contains laterally continuos, horizontal reflectors which represent flood plain deposits. As mapped using GPR data, the toe of the older debris field appears truncated by the Fraser River, suggesting that landslide debris once extended further across the valley bottom.
